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 -
Study on core loss of high silicon steel motor stator considering temperature and compressive stress
Since the motor core is often affected by various physical factors such as magnetic field, temperature field, stress field, and frequency during the working process; at the same time, different processing factors such as residual stress generated by stamping and shearing of silicon steel sheets, ...Read more -
The wishful thinking behind Tesla’s “removal of rare earths”
Tesla is now not only planning to subvert the electric vehicle market, but also preparing to point the way to the electrical industry and even the technology industry behind it. At Tesla’s global investor conference “Grand Plan 3” on March 2, Colin Campbell, Tesla’s vice president of powertrain ...Read more -
How to choose a “real material” motor?
How can we buy genuine motors at a fair price, and how to distinguish the quality of the motor? There are many motor manufacturers, and the quality and price are also different. Although my country has already formulated technical standards for motor production and design, many companies have a...Read more -
Detailed questions and answers about motor technology, decisive collection!
