Motor IE3
With a century of motor development experience, Hitachi provides a new generational motor.
Main Features
- Global standard
- Conformity to JIS C 4213(Japan) [Efficiency class: IEC60034-30 Premium efficiency class (IE3)]
- High-efficiency
- Compare to the standard motors, iron core shape is improved and material quality is raised
- Motor loss is reduced 30~40%
- This improvement realizes higher efficiency when compared with the standard motors
- Long motor life
- The temperature of stator coil has been decreased at 10~20C under a rationalization design and a high cooling effect for an electric part
- The coil insulation is achieved two times longer on operation life compared with the standard motor
- The bearings are also 2.5 times longer on operation life
- The operation life changes depending on operation conditions
- Inverter operation is also available (1:10 or 1:20 constant torque)
- 0.4~1.5kW 4P is available to operate with 1:10(6~60Hz) speed under 100% constant torque operation using the inverters (In case the sensorless vector inverters are used) 1: 20(3~60Hz) is also available with special design motors. These motors are adopted durable insulation system with advanced technology.
- Furthermore benefit
- Low noise and vibration can be realized with advanced technologies
