Technical Information
Hoyer AC IE4 electric motors are manufactured according to the efficiency class system specified under IEC 60034-30. Their high quality, reliability and performance are well documented.
The motors are asynchronous, low voltage three-phase TEFC motors.
Motors in size 80-200 have closed bearings greased for life. All Hoyer IE4 motors have a locked bearing in the drive end as standard. Other voltages are supplied on request.
IE4 motors meet the EU's tightened super-premium efficiency requirements for motors in the 75-200 kW range. Documented compliance and lower running costs.
Part of the EU's broader initiative to raise energy efficiency and reduce environmental impact across industrial practices.

What to Consider When Selecting an IE4 Motor
Duty cycle and load
Consider how the motor will operate over time. IE4 motors are particularly well suited to continuous, high-load applications where energy efficiency can make a significant difference.
Power and speed requirements
The motor’s power rating and speed should match the specific requirements of the application to ensure reliable and efficient operation.
VFD and control compatibility
If the motor is used with a variable frequency drive (VFD), compatibility between the motor, drive and control setup is essential to achieve the intended performance and efficiency.
Operating environment
Ambient temperature, humidity and other environmental conditions can affect motor performance and lifetime and should therefore be considered when specifying the motor.
Long-term energy efficiency
IE4 motors can reduce energy consumption over their operating lifetime, supporting lower operating costs as well as your organisation’s energy and sustainability targets.
