Motor Vibration Test Methods
1. Causes of motor vibrationBefore understanding how to measure motor vibration, you first need to understand the causes of motor vibration. Motor vibration is usually caused by the following reasons:1. The internal structure of the motor is loose or severely worn2. The motor bearing is worn or damaRead more -
What is the difference between a synchronous motor and an asynchronous motor?
The main differences between synchronous motors and asynchronous motors include starting mode, working principle, speed control, power factor, overload characteristics, application range, structural complexity and other aspectsLet's explain the differences in each aspect one by one:Starting modeRead more -
The difference between the star connection and the triangle connection of the motor
In triangle connection: each winding of the three-phase motor bears the line voltage (380V),In star connection: each phase voltage of the motor bears (220V).When the motor power is the same, the winding current of the triangle motor is less than the winding current of the star connection motor.WhenRead more -
What is the role of the commutator in a DC motor
The commutator is a key component in a DC motor, which is mainly used to change the direction of the current, thereby realizing the forward and reverse rotation of the motor. In the operation of the Cima motor, the commutator plays a vital role, and its performance directly affects the efficiency anRead more -

Prepare toolsReplacing motor carbon brushes requires some basic tools, such as wrenches, screwdrivers, pliers, brushes, etc. Before starting the replacement, make sure you have these tools ready.2. Disassemble the motorFirst, you need to disassemble the motRead more -
How can the motor shaft wear be repaired?
1. Wear of the motor shaft bearing, wear of the motor bearing chamber, and wear of the shaft head keyway.Traditional repair methods: mainly brush plating, spraying, surfacing or replacement. Brush plating is easy to delaminate and the replacement cost is high, which makes it difficult to solve the pRead more -
A Brief Analysis of the Most Commonly Used Braking Methods for Three-phase Asynchronous Motors
Mechanical and electrical braking is a method of using a mechanical mechanism to quickly shut down the motor for braking. Electromagnetic braking is a common mechanical brake. Electric braking is used to generate torque in the direction of speed, and the motor decelerates quickly. Generally speakingRead more -
Why Do Motors Adopt Deep Slotted Rotors?
In the previous topic we talked about motor starting, efficiency and other performance parameters of the relationship between the fish and the bear's paw is a very desirable effect, but how to try to achieve, is indeed a topic of motor research.We have talked about, the starting process we expecRead more
