euromotori motors refer to low-power single-phase asynchronous motors powered by a single-phase AC supply (AC220V). These motors typically have two-phase windings on the stator and a standard squirrel-cage rotor. Different distributions of the two-phase windings on the stator and different power supply conditions can produce different starting and operating characteristics.

euromotori motor speed control

Motor speed control mostly adopts the method of adjusting voltage, which means changing the electromotive force. Based on their mechanical characteristics, factors affecting motor speed include electromotive force, magnetic flux, and the number of armature conductors. For manufactured motors, the number of conductors is fixed and cannot be changed, so this method cannot be used. If the method of changing magnetic flux is adopted, it requires connecting an adjustable resistor in parallel at the excitation coil, but this resistor consumes significant power and is bulky, making it neither simple nor economical. Adopting the voltage adjustment method using thyristor speed control technology features simple circuits and small component sizes, making it a simple and effective method. The voltage speed control method for single-phase series-wound motors uses controllable phase-shifting voltage regulation, utilizing the thyristor's trigger voltage lagging behind the input voltage to achieve phase-shifted triggering of the input voltage. Implementation methods include hardware and software approaches. In hardware design, to achieve reliable motor speed control, dedicated integrated circuits are used as control circuits, and speed sensors are installed on the motor shaft to feedback speed signals, thereby keeping the set motor speed stable regardless of load changes. However, these high-performance speed control devices lack competitiveness in actual household appliance speed control due to complex circuits, high costs, and large sizes. Using software methods, only a microprocessor needs to be added in hardware; the control algorithm program is written into the microprocessor, which triggers the delayed conduction of the thyristor to achieve speed control of the series-wound motor. This method has a relatively simple circuit and can be completed using a microcontroller, saving costs. Therefore, this method is widely used in practical applications. Based on the controllable phase-shifting rectification method, there are full-wave rectification and half-wave rectification. Similarly, speed control methods for series-wound motors are also divided into full-wave and half-wave. Using half-wave rectification, during the positive half-cycle of the AC power sine signal, due to the characteristics of the thyristor, when an appropriate positive pulse signal is given after a delay time, the thyristor conducts, and the series-wound motor receives power excitation to operate. Different delay times correspond to different voltage excitations, causing the motor to output different speeds, thus achieving speed control. The principle of the full-wave method is the same as that of the half-wave method, using a triac. During the negative half-cycle of the AC sine signal, control pulses are given to the thyristor to control the system's input power voltage. In this way, the motor's speed signal is adjusted twice within one power cycle, improving the system's response speed, timely adjusting the motor speed to make operation smoother, and providing a wider speed control range.

Based on the different working power supplies of motors, they can be divided into DC motors and AC motors. Among them, AC motors are further divided into single-phase motors and three-phase motors. Based on different structures and working principles, motors can be divided into DC motors, asynchronous motors, and synchronous motors. Synchronous motors can be further divided into permanent magnet synchronous motors, reluctance synchronous motors, and hysteresis synchronous motors. Asynchronous motors can be divided into induction motors and AC commutator motors. Induction motors are further divided into three-phase asynchronous motors, single-phase asynchronous motors, and shaded-pole asynchronous motors. AC commutator motors are further divided into single-phase series-wound motors, AC/DC universal motors, and repulsion motors. DC motors can be divided into brushless DC motors and brushed DC motors based on structure and working principles. Brushed DC motors can be divided into permanent magnet DC motors and electromagnetic DC motors. Electromagnetic DC motors are further divided into series-wound DC motors, shunt-wound DC motors, separately excited DC motors, and compound-wound DC motors. Permanent magnet DC motors are further divided into rare-earth permanent magnet DC motors, ferrite permanent magnet DC motors, and Alnico permanent magnet DC motors. Based on different starting and operating methods, motors can be divided into capacitor-start single-phase asynchronous motors, capacitor-run single-phase asynchronous motors, capacitor-start-run single-phase asynchronous motors, and split-phase single-phase asynchronous motors. They can be divided into drive motors and control motors. Drive motors are further divided into motors for power tools (including drilling, polishing, grinding, slotting, cutting, reaming, and other tools), motors for home appliances (including washing machines, electric fans, refrigerators, air conditioners, recorders, VCRs, DVD players, vacuum cleaners, cameras, hair dryers, electric shavers, etc.), and motors for other general small mechanical equipment (including various small machine tools, small machinery, medical devices, electronic instruments, etc.). Control motors are further divided into stepper motors and servo motors. Based on different rotor structures, motors can be divided into cage-type induction motors (formerly known as squirrel-cage asynchronous motors) and wound-rotor induction motors (formerly known as wound-type asynchronous motors). Based on different operating speeds, motors can be divided into high-speed motors, low-speed motors, constant-speed motors, and variable-speed motors. Low-speed motors are further divided into gear reduction motors, electromagnetic reduction motors, torque motors, and claw-pole synchronous motors. Variable-speed motors, in addition to being divided into stepped constant-speed motors, stepless constant-speed motors, stepped variable-speed motors, and stepless variable-speed motors, can also be divided into electromagnetic variable-speed motors, DC variable-speed motors, PWM variable-frequency variable-speed motors, and switched reluctance variable-speed motors. The rotor speed of an asynchronous motor is always slightly lower than the synchronous speed of the rotating magnetic field. The rotor speed of a synchronous motor remains at synchronous speed regardless of the load size. 1, horizontal vibration motor: (1), loosen the protective cover fastening screws and remove the protective covers at both ends; (2), for vibration motors with excitation force less than MV50-2, MV50-4, MV50-6, MV30-8 (excluding these four specifications), the outer eccentric block is an adjustable block with a scale indicating the maximum excitation force percentage on the surface, and the inner eccentric block is a fixed block, both clamped onto the motor shaft using fastening bolts. Reference lines are engraved on both end faces of the shaft. Loosen the clamping bolts of the outer eccentric blocks on both sides, rotate the outer eccentric blocks on both sides in the same direction so that the engraved line on the shaft aligns with the excitation force scale line on the outer eccentric block, adjust to the required excitation force, tighten the clamping bolts of the outer eccentric blocks, and install the protective covers; (3) excitation force greater than or equal to MV50-2;

The motor drive current is purely AC; brushless DC motors can be further divided into brushless speed motors and brushless torque motors. Generally, there are two types of drive currents for brushless motors: one is trapezoidal wave (usually "square wave"), and the other is sine wave. Sometimes the former is called a DC brushless motor, and the latter is called an AC servo motor, which is strictly speaking a type of AC servo motor. To reduce rotational inertia, brushless DC motors usually adopt a "slender" structure. Brushless DC motors are much smaller in weight and volume than brushed DC motors, and the corresponding rotational inertia can be reduced by about 40%—50%. Due to processing issues with permanent magnet materials, the general capacity of brushless DC motors is below 100kW. These motors have good linearity in mechanical and adjustment characteristics, wide speed control range, long life, convenient maintenance, low noise, and do not have a series of problems caused by brushes, so these motors have great application potential in control systems. The stator windings of the motor are mostly made into a three-phase symmetrical star connection, very similar to three-phase asynchronous motors. The rotor of the motor is bonded with magnetized permanent magnets. To detect the polarity of the motor rotor, position sensors are installed inside the motor. The driver consists of power electronic devices and integrated circuits, etc., and its functions are: to accept start, stop, and brake signals of the motor to control the start, stop, and braking of the motor; to accept position sensor signals and forward/reverse signals to control the on/off of each power tube in the inverter bridge to generate continuous torque; to accept speed commands and speed feedback signals to control and adjust the speed; to provide protection and display, etc. Since brushless DC motors operate in a self-controlled manner, they do not require additional starting windings on the rotor like synchronous motors under heavy-load start with variable frequency speed control, nor do they produce oscillation and loss of synchronism during sudden load changes. The permanent magnets of small and medium-capacity brushless DC motors mostly use high-energy-product rare-earth neodymium-iron-boron (Nd-Fe-B) materials. Therefore, the volume of rare-earth permanent magnet brushless motors is reduced by one frame size compared to three-phase asynchronous motors of the same capacity. Research on variable frequency speed control of asynchronous motors over the past thirty years has ultimately been seeking methods to control asynchronous motor torque. Rare-earth permanent magnet brushless DC motors will surely show advantages in the field of speed control due to their wide speed control, small volume, high efficiency, and small steady-state speed error. Because brushless DC motors have the characteristics of DC brushed motors and are also frequency-changing devices, they are also known as DC variable frequency, with the internationally common term being BLDC. The operating efficiency, low-speed torque, speed accuracy, etc., of brushless DC motors are better than inverters of any control technology, so they deserve industry attention. This product has been produced exceeding 55kW, can be designed up to 400kW, and can meet the industry's needs for energy saving and high-performance drive.
