Details:
JG2 series motors are three-phase asynchronous motors dedicated to enclosed self-cooling roller tables.

This series of motors have the characteristics of large locked-rotor torque, dynamic constant, thermal stability and reliability. It can work under heavy loads such as frequent starting, brake reversal and harsh conditions such as heat, humidity and dust.

This series of motors are suitable for the driving of the transfer roller table and work roller table of the metallurgical industry steelmaking, steel rolling, continuous casting machine and other equipment, and can also be used for the driving of other machinery.

Motor operating conditions

Ambient temperature: -15℃~+40℃ Working system: S1, S3, S5 Altitude: ≤1000m Protection grade IP54

Power supply voltage: 380V, three-phase Insulation class: H class Rated frequency: 50Hz Cooling method: IC0410

The motor can be used at any frequency within the range of 10~70Hz or can be operated with variable frequency speed regulation. At this time, the voltage changes in direct proportion to the frequency, but the torque, power, current, and dynamic constants will also change at this time.

Installation method

This series of motors have two installation structure types

(1) Type B3 (horizontal, base with feet)

(2) B5 type (horizontal type, base without feet, end cover with flange)

Technical data

  Dynamic constant one represents an important performance index of the motor's working ability. The higher the dynamic constant, the higher the motor's negative FC-load duration rate, that is, the percentage of the duty cycle at the point of power-on operation.
