Motor shaft searches are generally made of high quality carbon steel. Choose 35#, 45#. Generally use 45# steel. These two materials are medium carbon steels, and their strength, rigidity and toughness can meet the working needs of the motor shaft. The motor shaft has high speed and low torque. It is made of 45# and does not require other heat treatment. The raw material is in a normalized state, and the raw material supply performance can meet the mechanical performance requirements of the motor shaft. The motor is represented by the letter M (the old standard is D) in the circuit. Its main function is to generate the driving torque. As the power source of the electric appliance or various machines, the generator is represented by the letter G in the circuit, its main The role is to use mechanical energy to convert into electrical energy. The motor should ensure good lubrication of the motor during operation. The general motor runs for about 5,000 hours, that is, the grease should be replenished or replaced. When the bearing is overheated or deteriorated during operation, the hydraulic pressure is changed in time. When replacing the grease, the old lubricating oil should be removed, and the oil groove of the bearing and the bearing cap should be cleaned by gasoline, and then the ZL-3 lithium base grease fills the cavity between the inner and outer rings of the bearing by 1/2 (for 2 poles). And 2/3 (for 4, 6, 8 poles).
