Working temperature of the brushless motor controller

by:Hoprio     2020-07-17

the working temperature of brushless motor controller and the structure of the brushless motor controller actually are the same, and most of the motor controller has a rotor, stator, end cover basic parts, such as winding is also made by permanent magnet and enameled wire, so the working temperature of brushless motor controller and other motor controller working temperature will be different? Just like everyone together to discuss the below. General motor controller in how high temperature can normal work? How high the temperature of the motor controller can afford? General motor controller of temperature rise should be below 20 degrees. If you measure the temperature of the motor controller housing more than the environment temperature above 25 degrees, suggests that the rise of temperature of the motor controller is beyond the normal range, general motor controller is composed of enameled wire winding coil, the enameled wire when the temperature higher than 150 degrees because temperature is too high and fall off of the paint film and the coil short circuit. The rise of temperature of the motor controller should be below 20 ℃, namely the temperature of the motor controller side housing more than the environment temperature should be less than 20 ℃, but what is the cause of the motor controller for more than 20 ℃ hot? Fever is the direct cause of motor controller caused by large current. Generally may be coil short circuit or open circuit, magnetic steel caused low efficiency of demagnetization of motor controller, the normal situation is the motor controller for a long time large current operation. Brushless motor controller due to the structure and the general motor controller is basically the same, just more than a hall sensor in the reversing internal, so the brushless motor controller working temperature is more than the environment temperature below 25 °, high temperature rise is also causes the coil short circuit, the phenomenon such as hall sensor failure. Also note that the environment temperature is generally under 40 °, if you want to work in over 40 ° environmental temperature, special high temperature treatment needs to be done.
