Sicme Motori motors refer to the engines that control the operation of mechanical components in servo systems; they are auxiliary motors serving as indirect speed-changing devices. Servo motors can control speed with very high positional accuracy, converting voltage signals into torque and rotational speed to drive controlled objects. The rotor speed of a servo motor is controlled by the input signal and responds rapidly. In automatic control systems, they serve as actuators, featuring small electromechanical time constants and high linearity, converting received electrical signals into angular displacement or angular velocity output on the motor shaft. They are divided into two main categories: DC and AC servo motors. Their main characteristic is that there is no self-rotation when the signal voltage is zero, and the speed decreases uniformly as torque increases.

Sicme Motori motor structure

Motor control structure: A brushless DC motor is a type of synchronous motor, meaning the rotor speed is influenced by the speed of the stator's rotating magnetic field and the number of rotor poles (P), where N = 120 · f / P. With a fixed number of rotor poles, changing the frequency of the stator's rotating magnetic field changes the rotor speed. A brushless DC motor adds electronic control (drive) to a synchronous motor, controlling the frequency of the stator's rotating magnetic field and feeding back the rotor speed to the control center for repeated correction, aiming to achieve characteristics close to those of a DC motor. This means that within the rated load range, a brushless DC motor can maintain a constant rotor speed even when the load changes. A brushless DC drive includes a power section and a control section: the power section supplies three-phase power to the motor, while the control section converts the input power frequency as required. The power section can accept direct DC input (typically 24V) or AC input (110V/220 V); if the input is AC, it must first be converted to DC by a converter (converter). Whether the input is DC or AC, before entering the motor windings, the DC voltage must be converted by an inverter (inverter) into 3-phase voltage to drive the motor. The inverter (inverter) generally consists of 6 power transistors (Q1 to Q6), arranged in upper arms (Q1, Q3, Q5) and lower arms (Q2, Q4, Q6), connected to the motor to act as switches controlling the current through the motor windings. The control section provides PWM (Pulse Width Modulation) to determine the switching frequency of the power transistors and the commutation timing of the inverter (inverter). Brushless DC motors are generally used in speed control applications where the speed must remain stable at the set value with minimal variation despite load changes. Therefore, the motor is equipped with Hall sensors (hall-sensor) inside to sense the magnetic field, serving as closed-loop speed control and as the basis for phase sequence control. However, this is used only for speed control and cannot be used for position control.

Sicme Motori motor applications

A motor refers to an asynchronous motor powered by a 220V AC single-phase power supply. Because 220V power supply is very convenient and economical, and household electricity usage is also 220V, single-phase motors are not only widely used in production but are also closely related to people's daily lives. Especially with the continuous improvement of living standards, the use of single-phase motors in household appliances is increasing. Production applications include micro water pumps, grinding machines, threshers, crushers, woodworking machinery, and medical devices. Domestic applications include electric fans, hair dryers, exhaust fans, washing machines, and refrigerators. There are many types, but the power ratings are relatively low. These motors typically have two-phase windings on the stator, and the rotor is of the standard squirrel-cage type. Different distributions of the two-phase windings on the stator and different power supply conditions can produce different starting and operating characteristics.

Sicme Motori motor fault handling

Incorrect motor winding connections result in an incomplete rotating magnetic field, causing symptoms such as difficult starting, unbalanced three-phase current, and high noise. If not handled promptly in severe cases, the windings may burn out. The main situations include: one or several coils in a pole phase installed in reverse or with head/tail connections swapped; pole (phase) groups connected in reverse; a phase winding connected in reverse; parallel branches of multi-path windings connected incorrectly; or incorrect "Delta" or "Y" connection methods. 1. Fault phenomena: The motor fails to start, no-load current is excessively large or unbalanced, temperature rises too quickly, there is severe vibration and loud noise, or fuses blow. 2. Causes: Mistakenly connecting a "Delta" configuration as a "Y" configuration; during maintenance, one of the three-phase windings has its head and tail reversed; inappropriate tap selection for reduced-voltage starting or internal wiring errors; incorrect winding connections during the initial installation of new motors; or incorrect identification of lead wires in old motors. 3. Inspection methods: (1) Ball rolling method. If a ball rolls along the inner circumferential surface of the stator, the connection is correct; otherwise, there is a wiring error. (2) Compass method. If the windings are correctly connected, the polarity indicated by a compass should reverse when passing adjacent pole (phase) groups in one phase, and also reverse for adjacent pole (phase) groups of different phases in the three-phase windings. If the polarity direction remains unchanged, one pole (phase) group is reversed; if the direction is indefinite, there are reversed coils within the phase group. (3) Multimeter voltage method. According to the wiring diagram, if the voltmeter shows no indication in two measurements, or shows a reading in one measurement and none in the other, it indicates reversed windings. (4) Other common methods include the dry battery method, milliammeter residual magnetism method, and motor rotation direction method. 4. Handling methods: (1) If a coil or coil group is reversed, resulting in significant no-load current imbalance, the motor should be returned to the factory for repair. (2) If lead wires are incorrect, correctly identify the head and tail ends and reconnect them. (3) If reduced-voltage starting connections are incorrect, carefully verify against the wiring or schematic diagram and rewire. (4) If wiring errors occur during the initial installation of new motors or after rewinding, send the motor to the factory for repair. (5) If one phase of the stator winding is reversed, the current in that phase will be exceptionally high; use this characteristic to locate the fault and perform repairs. (6) If a "Y" connection is mistakenly made as a "Delta" connection, or if the number of turns is insufficient, the no-load current will be high; correct this promptly.
