Stepper motor is the electrical pulse signal into angular displacement or linear displacement of the open-loop control element stepper motor parts. In the case of non-overload, the motor speed, stop position depends only on the pulse signal frequency and the number of pulses, and not affected by load changes, when the stepper drive receives a […]

1, the motor connected to the power start, the motor does not turn but a buzz sound may be: ① due to the power of the problem, resulting in single-phase operation; ② motor overload capacity; ③ drag mechanical stuck; ④ winding motor rotor circuit open into a broken line; ⑤ stator head end of the […]

Four kinds of motor temperature measurement method There are four main methods of motor temperature measurement: ① thermometer method; ② resistance method; ③ embedded thermometer method; ④ paste temperature measurement method. The temperature test described here uses the first method described above. The temperature sensor is a copper-constantan thermocouple that is easier to manufacture, less […]

1, the electromagnetic torque of the synchronous motor is the interaction between the stator rotating magnetic field generated by the power supply voltage and the main magnetic field of the rotor; 2, the stator rotating magnetic field and the rotor main magnetic field axis of the magnetic angle called angle; 3, the power angle is […]

Servo motor debugging method 1, initialization parameters Before wiring, initialize the parameters. On the control card: Select the control mode; Clear the PID parameters; Turn off the default enable signal when the control card is powered on; Save this state to ensure that the control card is powered on again. In the servo motor: set […]

1, the problem of motor efficiency and temperature rise No matter what form of frequency converter The English translation of the frequency converter is VFD (Variable-frequencyDrive), which may be one of the few examples of modern technology from Chinese reverse translation to English. (But VFD can also be interpreted as Vacuum Fluorescent Display, vacuum fluorescent […]
