Description

technical field

[0001] The invention relates to an elevator driving device. Background technique

[0002] Existing traction machine, such as the disclosed elevator traction machine of Chinese invention patent (notification number CN1141775C). The electromagnet and the brake arm of the traction machine are arranged outside the traction machine, and the brake arm acts on the brake wheel of the outer rotor of the traction machine to generate a braking force, thereby braking the traction machine. The disadvantages of this invention are: 1) because the brake wheel of the traction machine is located on the same side as the traction wheel and is arranged adjacently, the brake surface is very easily affected by the grease of the steel wire rope like this, thereby causing the friction coefficient of the brake surface to decrease , the normal operation of the elevator has a catastrophic impact; 2) Since the brake is set outside the traction machine, the noise of the brake is directly...
