Details
Tips: Technical Characteristics of Variable Speed Motor.
1. High efficiency
Reach the second level of the European CEMEP-EU efficiency class motor standard.
2. Dual bandwidth voltage
The voltage range is 220V~690V, suitable for 50Hz and 60Hz power supplies.
3. Low noise
By optimizing electromagnetic design, ventilation conditions, structural dimensions and other technologies, the noise of M2JA series motors is lower.
4. High bearing load capacity
The motor uses deep groove ball bearings, which has a long life. The 80-132 center height motor is permanently lubricated, and 160-355 is equipped with a refueling device.
5. Good reliability
The motor is a fully enclosed air-cooled structure, with a protection level of IP55, and the materials and processes meet environmental requirements. The motor has high mechanical strength, sturdiness and durability, and strong anti-rust and anti-corrosion performance. Winding reliability is good, using F-level insulation structure, and B-level assessment. And can add PTC thermistor or thermal switch according to user needs.
