Technical Information
Hoyer IE3 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 size 80-200 have closed bearings greased for life, with a locked bearing in the drive end as standard on all Hoyer IE4 motors. Other voltages are supplied on request.
Key Benefits
Significant energy savings
With their high efficiency, IE3 motors reduce energy consumption, leading to lower electricity costs over time.
Enhanced operational efficiency
IE3 motors deliver high performance under varied load conditions, with compatibility for variable frequency drives (VFDs) for precise speed control, ensuring reliable operation across your industrial applications.
Versatility in applications
Whether it’s manufacturing, processing, marine or wind applications, IE3 motors deliver consistent, reliable performance across your industry.
Reduced carbon footprint
By consuming less power, IE3 motors contribute to a lower carbon footprint, helping you achieve your sustainability goals and environmental targets.
IE3 Motors for Efficient, Reliable Performance
Hoyer IE3 motors are designed for reliable performance across diverse industrial applications. Compatibility with VFD systems enables variable speed control, providing greater flexibility and helping improve process control and energy efficiency.
With a higher efficiency level, IE3 motors convert a greater share of electrical energy into mechanical energy, helping reduce energy consumption in operation. This is particularly valuable in applications where motor speed needs to be precisely controlled.
Our range includes various IE3 models engineered for specific application requirements, helping ensure a fit-for-purpose motor solution.
What to Consider When Selecting an IE3 Motor
Duty cycle and load
Consider how the motor will operate over time. IE3 motors are most efficient under constant, high-load conditions.
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
IE3 motors often offer long-term savings through reduced energy consumption, so it’s worth factoring in the total cost of ownership rather than just the initial purchase price.
