The superior field-weakening capability of IPMSMs implies a comparison, with the counterpart being Surface-Mounted Permanent Magnet Synchronous Motors (SPMSMs). On field-weakening Why is field-weakening necessary? Torque output of a motor is co...

The basic conditions for current formation are voltage and a closed loop. The prerequisite for generating shaft current is the presence of shaft voltage and a closed loop. So why does shaft voltage occur in motors operating at power frequency? During the operation of rotating motors, there are ...

How to Prevent Motor Shaft Breakage? We have conducted numerous discussions on the cause analysis of shaft breakage combined with fault cases. The principle for preventing shaft breakage is to reduce and eliminate stress points and exclude external force factors. From the perspective of the sha...

There are two types of motor shaft currents: low-frequency and high-frequency. Due to alternating magnetic flux, static charge accumulation, and asymmetry caused during motor manufacturing, the generated shaft current usually has a low frequency, belonging to low-frequency shaft current. Genera...

When the surface of a solid medium is contaminated and becomes damp, the soluble salts, acids, and alkalis contained in the contamination layer dissolve in the water film, forming ionic conductivity, causing a large leakage current to pass through the contaminated surface; the surface flashover...

For electric motor products, when they are produced strictly according to the design parameters and process parameters, the speed difference of motors of the same specification is very small, generally not more than two revolutions. For the motor of a single-machine driving device, there is no ...

In the previous tweet, we talked about the starting operating characteristics of asynchronous motors, which are also called induction motors. This involves the electromagnetic torque of the motor, which is generated by the fundamental magnetic field in the air gap and the rotor current induced ...

In the exploration and practice of the motor field, a clear understanding of the relevant mandatory national standards is the key to ensuring motor performance, safety and energy efficiency. For professionals working in the motor field, the following five mandatory national standards are the co...

The most widely used bearing in motor products is the rolling bearing. The rolling bearing is a standardized component with advantages such as low friction, easy starting and simple replacement. When we are engaged in daily maintenance or mechanical design, it is crucial to choose the bearing m...
