Energy generation

Power generation mainly includes the application of electric motors and generators. Its motor and generator do not have two identical applications.

General purpose motors

Reliable operation is necessary. Typograph motors are generally small to medium-sized, ranging from 1 to 500 kW, with high output and generally not sold on shelves. Energy efficiency, reliability, and trouble-free operation are key to improving productivity.

Motors for specific applications

Shanghai Gegang Bearing Co., Ltd. provides convincing performance for customers in various industries when motors for specific applications are not available in general.

Extra large motor

Extra large motors are expensive bearing requirements. In large motors, the most common type of bearing is a combination of hydrodynamic bearings and bearing pedestals. Hydrodynamic bearings, also known as sliding bearings, are very expensive in configuration and typically account for up to 8% of machine costs. However, there are also many large-scale motor applications that do not actually require fluid dynamic bearing technology.

Control motor

For the need for control. The increasing demand for precision and variable processes, as well as the increasing focus on achieving potential energy-saving, require the controllability of motors.

Motors with stray current issues

Motors with stray current problems are susceptible to the influence of stray currents. In an electric motor, stray current can cause small pits to form on the surface of the bearing raceway and rolling element. Especially variable speed drive motors with pulse width modulation frequency conversion are more dangerous. Over time, the destructive effects of stray bearing currents can lead to increased noise and heat, decreased lubricant effectiveness, excessive vibration, and ultimately premature bearing failure.
