Knowledge in motor manufacturing: How much bearing clearance is more reasonable? Why should the bearing be preloaded?
Bearing system reliability is always a hot topic in electric motor products. We have talked a lot in previous articles, such as bearing sound problems, shaft current problems, bearing heating problems and so on. The focus of this article is the clearance of the motor bearing, that is to say, unde...Read more -
High-efficiency, energy-saving and consumption-reducing control of motor frequency conversion and speed regulation
The frequency conversion and speed regulation operation of the motor has gradually become a symbol of the times. The speed regulation of the synchronous motor is the frequency conversion and speed regulation control of the square torque load machinery such as the fan and the pump driven by the fr...Read more -
Coaxiality Requirement and Realization of Motor Frame
The frame is a very critical part of the motor. Compared with parts such as end covers, since the iron core is pressed into the frame, it will become a component that is not easy to disassemble. Therefore, people should pay more attention to the quality compliance of the frame. Some. The diamet...Read more -
Motor quality problems caused by unsuitable bearings
Motor bearings are always the most discussed topic in motor products. Different motor products need corresponding bearings to match them. If the bearings are not selected properly, there may be problems such as noise and vibration that directly affect the performance of the motor. impact on servi...Read more -
The random inspection of the whole motor is generally not disassembled for inspection
Quality supervision and random inspection is a means for the country to supervise and inspect product quality from different levels and scopes, and motor products are no exception; but from the entire development process of motor product quality supervision and random inspection, motor quality ra...Read more -
When the direction of the left, right, and top outlets of the motor changes, will it affect the rotation of the motor?
The direction of rotation is one of the important quality properties of motor products. If the customer has no special requirements, the motor manufacturer will manufacture it in a clockwise direction, that is, after wiring according to the phase sequence marked on the motor, the motor should rot...Read more -
Several development trends of industrial drive motors
Just casually talk about several development trends of industrial drive motors, welcome to correct me! The most widely used is the cage-type asynchronous motor, and its technological progress highlights the application of thin-gauge silicon steel sheets. Low-voltage direct grid-connected operati...Read more -
Summary of Fatal Faults in Drive Motor System of New Energy Vehicles
1 Fault name: stator winding Failure Mode: Burnout Fault description: The motor windings are burned out due to short circuit or high operating temperature of the motor, and the motor needs to be replaced 2 Fault name: stator winding Failure Mode: Breakdown Fault description: The insulation breakd...Read more -
How does the magnet wire match the motor insulation class?
For different series of motors, the materials or parts of the motor winding and bearing system will be determined in combination with the actual operating conditions of the motor. If the actual operating temperature of the motor is high or the temperature rise of the motor body is high, the beari...Read more -
Why is the speed of the motor getting higher and higher driven by cost?
foreword At the “2023 Dongfeng Motor Brand Spring Conference” on April 10, the Mach E new energy power brand was released. E stands for electric, high efficiency, energy saving and environmental protection. Mach E is mainly composed of three major produc...Read more -
Energy saving analysis of super high efficiency permanent magnet motor replacing Y2 asynchronous motor
Foreword Efficiency and power factor are two different concepts. The efficiency of the motor refers to the ratio of the shaft output power of the motor to the power absorbed by the motor from the grid, and the power factor refers to the ratio of the active power of the motor to the apparent po...Read more -
Motor vibration case sharing
Ms. Shen’s good friend, old W, works in a certain repair shop. Because of the same major, the two naturally have more topics on faulty motors. Ms. Shen also has the privilege and opportunity to see motor fault cases. Their unit has undertaken a H355 2P 280kW cast aluminum rotor motor. The custome...Read more
