GB series single-phase resistance starting asynchronous motorDetailed product description：

The GB series single-phase resistance starting asynchronous motor complies with the relevant provisions of the international IEC standard.
The basic components of this series of motors are made of steel plate structure, with E-class insulation, suitable for mechanical equipment that does not require too much starting torque, such as small machine tools, blowers, etc.
The GBO series motor is fully enclosed with an enclosure protection level of IP44.
The GBK series motor is of anti drip protection type, with a shell protection level of IP23.
There are four installation methods for motors:
1. IMB3 type - The machine base has feet and the end cover has no flange.
2. IMB34 type - The machine base has feet, a small flange on the end cover, and the shaft extends at the flange end.
3. IMB14 type - The machine base has feet, a small flange on the end cover, and the shaft extends at the flange end.
4. IMB3K type - The machine base has feet, the end cover has no flange, and the casing and end cover have ventilation holes.
