Brief Introduction

 

In industrial production, electric motors, especially three-phase squirrel cage asynchronous motors, have a wide range of applications. This type of electric motor is quiet and stable, making it an important part of most systems, including compressors. The electric motor mainly consists of two parts: the stator and the rotor. The stator is a stationary part that generates a rotating magnetic field, while the rotor converts the energy of this magnetic field into mechanical energy.

The stator is connected to a three-phase power supply, and the current in its winding enhances the rotating magnetic field, thereby generating current in the rotor and strengthening the magnetic field. The interaction between the magnetic fields of the stator and rotor generates torque, causing the rotor shaft to start rotating.

Motor speed

Regarding the speed of an electric motor, theoretically, if the shaft rotation speed of an asynchronous motor is synchronized with the magnetic field, the induced current on the rotor will be zero. However, in reality, due to the loss of bearings and other factors, the rotational speed of the shaft is always 1-5% slower than the synchronous speed of the magnetic field (this phenomenon is called "slip").

The efficiency of an electric motor is not non-destructive. It always generates losses when converting energy, mainly including resistance losses, ventilation losses, magnetization losses, and friction losses.

The insulation level of electric motors is classified according to the IEC60085 standard, which was proposed by the International Electrotechnical Commission. Different insulation materials are classified according to temperature, using letters to represent their levels. This temperature value is the highest temperature that the insulation material can withstand. If the temperature exceeds this limit by 10 ℃ and continues for a period of time, the lifespan of the insulation material may be halved.
