Technical Field

[0001] The utility model relates to the technical field of electric vehicle motor production, in particular to a protective device for the safe production of electric vehicle motors. Background Technique

[0002] At present, permanent magnet DC motors are generally used in electric vehicle motors. Electric vehicle motors can be divided into two categories: brushed motors and brushless motors according to the power supply form of the motor; according to the mechanical structure of the motor assembly, they are generally divided into two categories: "toothed" (the motor speed is high and needs to be decelerated by a gear) and "toothless" (the motor torque output does not go through any deceleration).
