Answer：Motor overload refers to the state where the current required by the motor during operation is greater than its rated current, causing the motor to operate overloaded. If this situation continues to occur, it will bring a series of serious consequenc...
Answer：when measuring the insulation resistance before the product is offline, it is best to conduct a hot insulation resistance test immediately after the product is undergoing an aging test, or after high-temperature aging. At this time, the measured resi...
Answer：By simply understanding the basic situation of the controller, we can have a rough idea and an impression of the importance of the controller. The controller is the second most expensive accessory in the whole vehicle assembly. According to the data ...
Answer：When the motor is running under load, its internal total loss is converted into heat energy, which increases the temperature of the motor. The insulation material in the motor has the poorest heat resistance. If the load of the motor is too large, th...
Answer：A servo motor is a micro motor used as an actuator in an automatic control device. Its function is to convert electrical signals into angular displacement or angular velocity of the rotating shaft.
Answer：Low-speed electric vehicles, in a broad sense, are all two-wheeled, three-wheeled, and four-wheeled electric vehicles with a speed of less than 70km/h. In a narrow sense, it refers to four-wheeled scooters for the elderly. The topic discussed in this...
Answer：The noise of electric motors can be divided into three categories: aerodynamic, mechanical and electromagnetic noise sources. In recent years, people have paid more and more attention to the impact of electromagnetic noise sources. This is mainly due...
Answer：When it comes to linear motors, the English name is linear servomotor. In fact, the motors we commonly see now are all rotary motors. From the history of the development of motors, we can talk about the various functional applications and advantages ...
Answer：When the voltage is reduced, the motor, as the core device of electric drive, will experience a series of significant changes. The following is a detailed analysis of these changes to help better understand the impact of voltage reduction on motor pe...
Answer：Reasons why the single-phase motor does not rotate and hums: (1) Single-phase operation due to power connection problems: (2) The motor is overloaded; (3) Stuck by the towing machinery; (4) The rotor circuit of the wound-rotor motor is open and disco...
