Why is Weak Magnetic Control Necessary for High-speed Motors?
01. MTPA and MTPV Permanent magnet synchronous motor is the core driving device of new energy vehicle power plants in China. It is well known that at low speeds, permanent magnet synchronous motor adopts maximum torque current ratio control, which means that given a torque, the minimum synthesize...Read more -
What reducer can be equipped with a stepper motor?
1. The reason why the stepper motor is equipped with a reducer The frequency of switching stator phase current in a stepper motor, such as changing the input pulse of the stepper motor drive circuit to make it move at low speed. When a low-speed stepper motor is waiting for a stepper command, the...Read more -
Motor: Flat Wire+Oil Cooling to Improve Motor Power Density and Efficiency
Under the traditional 400V architecture, permanent magnet motors are prone to heating and demagnetization under high current and high speed conditions, making it difficult to improve the overall motor power. This provides an opportunity for the 800V architecture to achieve increased motor power u...Read more -
Comparison of Motor Power and Current
Electricmachinery (commonly known as “motor”) refers to an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. The motor is represented by the letter M (formerly D) in the circuit, and its main function is to generate driv...Read more -
How to Reduce Motor Iron Loss
Factors affecting basic iron consumption To analyze a problem, we first need to know some basic theories, which will help us understand. Firstly, we need to know two concepts. One is alternating magnetization, which, to put it simply, occurs in the iron core of a transformer and in the stator or ...Read more -
