The glitches that motor cannot get used to

Why do motors generate shaft currents? The current in the shaft-bearing housing-base circuit of a motor is called shaft current. Causes of shaft currents:[1] 1. Asymmetry of the magnetic field; 2. Harmonics in the supply current; 3. Poor manufacturing and installation, uneven air gap due to rotor eccentricity; 4. Gaps between two semicircles of the…

Reasons and preventive measures for demagnetization of PMSM

Introduction The permanent magnet synchronous motor is a synchronous motor that uses permanent magnets to establish an excitation magnetic field. Its stator generates a rotating magnetic field, and the rotor is made of permanent magnet materials. Once the permanent magnet motor loses its magnetism, basically you can only choose to replace the motor, and the…

What is a Bushless dc motor？

Before understanding what a brushless motor is, let’s first understand what a motor is. Motor refers to an electromagnetic device that realizes the conversion or transfer of electrical energy according to the law of electromagnetic induction.   understand? Is it more confusing? Simply put, because electricity cannot directly make a machine move directly, it needs…

X-TEAM XT60B EC Motor for fascia gun & Medical Devices

X-TEAM XT60B EC Motor for fascia gun & DC fan & range hood Product advantages: 1. During the operation of the brushless motor, no electric spark will be generated, which reduces the interference of the electric spark to the remote control radio equipment. 2. The friction force is small during operation, the operation is smooth,…
