AViTEQ motor Germany AViTEQ model AViTEQ price

AViTEQ motors are named for their armature winding and field winding connected in series. Single-phase series-wound motors are AC/DC universal motors; they can operate on either AC or DC power supplies. The single-phase series-wound motor is widely used. Its advantages include high speed, high starting torque, compact size, light weight, resistance to stalling, and a wide applicable voltage range. Speed control can be achieved simply and easily by adjusting the voltage.

AViTEQ motor development trends

Permanent magnet synchronous motors are gradually being widely used in industrial production and daily life due to their high efficiency, high power density, simple structure, and significant energy-saving effects. In particular, the successful development of high-temperature-resistant, high-performance neodymium iron boron permanent magnets in recent years, along with further development and improvement of power electronic components, has ushered in a new era for the research and development of rare-earth permanent magnet synchronous motors both domestically and internationally. This will lead to qualitative leaps in both theoretical research and application fields. Current development is trending toward ultra-high speed, high torque, high power, miniaturization, and high functionality. Permanent magnet synchronous motors do not require field windings, have a relatively simple structure, have no heat source in the magnetic field section, and do not require cooling devices. The high coercivity of the materials allows for a larger air gap length, making it possible to significantly increase rotational speed. Due to the high maximum energy product of neodymium iron boron permanent magnets, especially the ability to manufacture ultra-thin permanent magnets, it has become possible to produce ultra-micro and low-inertia motors that were previously difficult to make. Ultra-small motors with diameters of less than a few millimeters have been developed as drive sources for medical micro-machines, robotic arms for eye surgery, or pipeline inspection robots. The world's smallest permanent magnet motor, with an outer diameter of 0.8mm and a length of 1.2mm, has now been produced.

AViTEQ motor speed control

Motor pole-changing speed control achieves speed regulation by changing the wiring configuration of the stator windings to alter the number of pole pairs in squirrel-cage motors. Variable frequency speed control changes the frequency of the stator power supply to the motor, thereby altering its synchronous speed. The main equipment in a variable frequency speed control system is the variable frequency drive (VFD) that provides the variable frequency power. VFDs can be divided into two categories: AC-DC-AC inverters and AC-AC inverters; AC-DC-AC inverters are predominantly used in China. Cascade speed control involves inserting an adjustable additional electromotive force into the rotor circuit of a wound-rotor motor to change the slip, thereby achieving speed control. Most of the slip power is absorbed by the inserted additional electromotive force, and then additional devices are used to return the absorbed slip power to the grid or convert the energy for utilization. Based on the method of absorbing and utilizing slip power, cascade speed control can be classified into motor cascade speed control, mechanical cascade speed control, and thyristor cascade speed control, with thyristor cascade speed control being the most commonly adopted. Inserting an additional resistor into the rotor of a wound-rotor asynchronous motor increases the motor's slip, causing the motor to run at a lower speed. The larger the inserted resistance, the lower the motor speed. This method features simple equipment and convenient control, but the slip power is dissipated as heat in the resistor. It constitutes stepped speed control with relatively soft mechanical characteristics. Changing the stator voltage of the motor yields a set of different mechanical characteristic curves, thereby obtaining different speeds. Since motor torque is proportional to the square of the voltage, the maximum torque drops significantly, resulting in a narrow speed control range, which makes this method difficult to apply to general squirrel-cage motors. To expand the speed control range, voltage-adjustment speed control should employ squirrel-cage motors with high rotor resistance, such as torque motors specifically designed for voltage-adjustment speed control, or connect frequency-sensitive resistors in series with wound-rotor motors. To expand the stable operating range, feedback control should be adopted for automatic speed regulation when speed control exceeds 2:1. The main device for voltage-adjustment speed control is a power supply capable of varying the voltage. Common voltage-adjustment methods include series saturable reactors, autotransformers, and thyristor voltage regulation, with thyristor voltage regulation being the optimal method.

AViTEQ motor classification

Types of motors: 1. Classification by power supply: Based on the working power supply, motors are divided into DC motors and AC motors. AC motors are further divided into single-phase motors and three-phase motors. 2. Classification by structure and operating principle: Motors are divided into DC motors, asynchronous motors, and synchronous motors based on structure and operating principle. Synchronous motors are further divided into permanent magnet synchronous motors, reluctance synchronous motors, and hysteresis synchronous motors. Asynchronous motors are 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 are divided into brushless DC motors and brushed DC motors based on structure and operating principle. Brushed DC motors are 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. 3. Classification by starting and running mode: Motors are 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 based on starting and running mode. 4. Classification by application: Motors are divided into drive motors and control motors based on application. Drive motors are further divided into motors for power tools (including drilling, polishing, grinding, slotting, cutting, reaming, etc.), 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. 5. Classification by rotor structure: Motors are divided into squirrel-cage induction motors (formerly known as squirrel-cage asynchronous motors under old standards) and wound-rotor induction motors (formerly known as wound-rotor asynchronous motors under old standards) based on rotor structure. 6. Classification by operating speed: Motors are divided into high-speed motors, low-speed motors, constant-speed motors, and adjustable-speed motors based on operating speed. Low-speed motors are further divided into gear reduction motors, electromagnetic reduction motors, torque motors, and claw-pole synchronous motors. Adjustable-speed motors are classified not only into stepped constant-speed motors, stepless constant-speed motors, stepped variable-speed motors, and stepless variable-speed motors, but also into electromagnetic adjustable-speed motors, DC adjustable-speed motors, PWM variable frequency adjustable-speed motors, and switched reluctance adjustable-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.
