IE2 Three Phase Asynchronous Induction Motors for Screw Compressor

ZYS series motor is special designed for compressor, frame size from 80 to 400, with insulation class F, tempreature rise is class B, under certain service factor the temperature rise is class F, special bearing is used when the service is 1.15 and 1.2 to ensure the bearing can operate for a long time, we can also make longer leads consider the cable of the motor connect with the electric cabinet of the compreesor directly, cable sheath is used for protection, and on both ends fixed with pipe cable glands, the dimensions of the pipe cable gland is indicated at the section of the terminal box, it featured high efficiency, energy saving, reliable performance, and it it suitable for continuous operation for the compressor.

Detail:
Operating conditions
Ambient temperature: -20senti degree≤ 0≤ 40senti degree
Altitude:lower than 1000 meters above sea level

Temperature and Insulation class
Motors are based on F (155ºC) ,B (80K),
to keep motor life and reliability

Cooling and Ventilation
Fully enclosed self fan cooling(TEFC).
Motor is fixed with auxiliary flow type
Plastic fan which is complying with
the provisions of 60034-6 IEC Ic411

Insulation class
Motor protection class is Ip55 which
can be used for dust or humidity
environment, and we can provide
a higher level of protection of motor

Motor protection
AS need, motor can be installed of PTC,
Pt100 and other winding resistance and
Bearing temperature measurement and
Protection device.

Voltage and frequency
The standard voltage is 220V/50Hz.
in the case of deviation
5%, the motor still can work good.

Vibration
Vibration speed of Ye3 series motor
in the no-load is in line with class A,
special requirement, we can provide
class B.

Terminals block box location
The terminal block box is on the
top or one the right side as the standard
Ye2 series motor.

Quality assurance
From design to produce factory,
we strictly follow the ISO9001 quality
certification system and procedures.
