IE3 electric motors
IE3 motors from Hoyer are recognised for proven high quality, reliability and performance. They are used for a wide variety of industrial, marine and wind applications.
Hoyer's range of IE3 motors
Hoyer's IE3 motors are designed to be versatile, capable of operating in diverse industrial environments. A feature of a Hoyer IE3 motor is the compatibility with VFD systems, which allows for variable speed control, further enhancing their efficiency and adaptability.
This feature is particularly beneficial in applications where motor speed needs to be precisely controlled, leading to improved process control and energy savings.
Our range of electric motors includes various IE3 models engineered to provide optimal performance in specific applications, ensuring that every industry can find a suitable IE3 motor solution from Hoyer.
Key factors to consider when selecting an IE3 motor
When selecting an IE3 electric motor, it's crucial to consider specific operational requirements.
First, assess the load profile: IE3 motors are most efficient under constant, high-load conditions. Evaluate the compatibility with existing systems, particularly if integrating with a Variable Frequency Drive (VFD).
Also, consider the environmental conditions, as IE3 motors have specific cooling and ventilation needs.
Lastly, factor in the total cost of ownership, not just the initial purchase price, as IE3 motors often offer long-term savings through reduced energy consumption.
These considerations ensure the selected IE3 motor optimally aligns with your operational needs and efficiency goals.
Are you looking for an electric motor with the highest efficiency and energy savings, the IE4 electric motor provides unmatched effectiveness.
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. Type HMA3 (aluminium) size 80-132 and HMC3 (cast iron) size 160-400 are supplied with SKF or similar premium bearings and 3xPTC in the windings. Motors in size 80-180 have closed bearings greased for life. All Hoyer IE3 motors have a locked bearing in the drive end as standard.
All IE3 motors are provided with blind caps in all supply connections and are IP55 as standard, prepared for drain holes and painted with RAL 9005 low gloss.
400 V Y – Hoyer IE3 motors ≤ 3 kW
400 V D – Hoyer IE4 motors ≥ 3 kW
Other voltages are supplied on request.

World Efficiency Motors
Did you know that Hoyer has developed a range of motors designed to meet different efficiency requirements across markets? The motors are based on our popular IE3 range.
We call them World Efficiency Motors.
As standard, Hoyer World Efficiency Motors are designed to IEC standard sizes and are UL/CSA approved. Likewise, Hoyer World Efficiency Motors are developed to meet the requirements of multiple efficiency class systems in one motor.
The range gives global OEMs many options when they need to optimize the supply chain and work with energy savings.
The technical excellence of IE3 motors
IE3 electric motors are designed to meet stringent energy efficiency standards, offering a significant leap over their predecessors.
This efficiency is measured in terms of reduced energy loss, higher output per unit of energy consumed, and lower operational costs. IE3 motors are designed with advanced electromagnetic designs, improved rotor structures, and high-quality insulation materials. These technical enhancements enable IE3 motors to operate more efficiently than IE1 motors and IE2 motors, leading to significant energy savings.
Hoyer's IE3 range exemplifies these advancements, offering motors that not only meet but often exceed the efficiency benchmarks set for this class.
