Title: MOTOR APPARATUS FOR HIGH VOLTAGE SWITCH DEVICE
Abstract:
A motor apparatus for a high voltage switch device, comprising a brushless DC motor (20), a drive and control apparatus (30), and a speed reduction apparatus (40). The brushless DC motor (20) comprises a rotor (202) and a stator (203). The rotor (202) is sleeved in the stator (203) and mounted in a motor housing (201). Two ends of the rotor (202) are respectively sleeved with rolling bearings (204), and the bearings (204) are sleeved on a motor drive shaft (208). The drive and control apparatus (30) comprises a microprocessor (301), a semiconductor switch (302), and a power supply module (303) for powering the microprocessor (301). The microprocessor (301) controls the start, stop, and forward and reverse rotation of the brushless DC motor (20) via the semiconductor switch (302). The speed reducer (40) comprises a gear transmission system (401) composed of a plurality of mutually meshing gears as well as an output shaft (402). The gear transmission system (401) transmits motion of the motor drive shaft (208) to the output shaft (402).
