The brushless motor is composed of a motor body and a driver, and is a typical mechatronic product. Since the brushless DC motor is operated in a self-controlled manner, it does not add a start winding to the rotor like a synchronous motor with a hea...
The insulating sleeve of the motor parts is completely free from cracks and looseness. The lead connections should be secure and the insulation resistance should not be less than 0.5 MΩ at a working temperature of 75 °C. In the brush device, the lowe...
1, the way of control is different Stepper motor: The angle of rotation is controlled by the number of control pulses, one pulse corresponding to one step angle. Servo motor: Control the rotation angle by controlling the length of the pulse time.Spin...
The washing machine motor speed of household washing machines varies from 400 rpm to 600 rpm and 900 rpm. It is the motor that rotates the washing machine. At present, the motors used in the washing machine basically have the following types: single-...
Detection of motor rotation: 1. Check if the resistance value of the motor running and starting winding is normal. For fully automatic washing machine 140W motor is used for 4Kg or less, main winding (yellow blue 28Ω), secondary winding (yellow red 2...
The speed of the motor is determined by the number of winding groups, such as a 4-pole motor (which refers to a motor with two pairs of magnetic poles). When the frequency is 50 Hz, the rated speed is 1450 rpm. In the case of a certain number of pole...
The motor, from the English motor, was transformed by Japanese and passed to China as a motor. Motor is the meaning of movement and maneuvering. Therefore, the motor is very wide. Pneumatic, electric, hydraulic and other electric motors are just one ...
(1) The terminal voltage is too low. Refers to the voltage measured at the motor stator lead end when the motor is started or at full load, not the no-load voltage. When the motor load is constant, if the voltage is reduced, the current will increase...
