Explosion proof variable pole multi speed three-phase asynchronous motorDetailed product description：

1、 Overview

The YBD80-280 explosion-proof variable pole multi speed three-phase asynchronous motor is a fully enclosed self fan cooled squirrel cage explosion-proof three-phase asynchronous motor derived from the YB2 series. This series of motors uses changing the winding connection to change the number of poles and output power of the motor, matching it with the load characteristics of the mechanical equipment, simplifying its variable speed system, and saving a lot of electricity. There are three types of electric motor speed changes: two speed, three speed, and four speed. There are 6 wiring bolts in the second speed junction box, 9 wiring bolts in the third speed junction box, and 12 wiring bolts in the fourth speed junction box for users to change poles and speed.

The explosion-proof performance of YBD80-280 explosion-proof variable pole multi speed three-phase asynchronous motor meets the requirements of GB3836.2-2000 "Electrical Equipment for Explosive Gas Environments Part 2: Explosion proof Type" d "", and is made into ExdIIAT4 ExdIIBT4, which is suitable for hazardous areas in factories with IIA, IIB levels and temperature groups T1 to T4 containing explosive gas mixtures.
The installation dimensions of this series of motors are the same as those of YB2 series motors.
The protection level of the motor body casing is IP55. Cooling method IC411.
Rated voltage of electric motor: 380V
Frequency: 50Hz
Working mode: Continuous (S1)
