Premium Efficiency Motors (IE3)

Application:

  • For fans, pumps and compressor.
  • Factories under long time operation.
  • For process machines for non stop operation.

Built as an advanced energy saving motor, the IE3 design features enhanced iron core construction and upgraded material quality to reduce energy loss by up to 30–40% compared to standard motors. This results in higher efficiency, lower operating costs, and improved overall productivity for industrial environments seeking long-term performance and energy savings.

Premium Efficiency Motors (IE3) are designed for high-demand industrial applications that require continuous, long-hour operation. Ideal for factories running non-stop, these energy saving motors deliver reliable performance and improved operational stability.

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 10~20°C 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 the 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
  • Operational cost saving
    – Considering the operation cost under long term period, the best idea is to adopt the high efficiency motors
    – The point is just not to consider the initial cost of motor but overall cost including long term operation
