High-efficiency Motors – Reduced Energy Costs and Environmental Protection

Increasing energy costs mean that energy consumption is of increasing significance in drive technology. It is essential to fully exploit potential for minimizing these costs in order to remain competitive now and in the future. Lower energy consumption also benefits the environment.

It is against this background that we are developing a new generation of low-voltage motors, enabling you to do more with your motors. Innovative copper rotors create the very best basis for highly efficient motors. The new motors for EFF1 (high efficiency) thereby offer large energy savings and are better for the environment. Also, the modular design concept provides full flexibility: each motor is based on a standardized concept for all international markets.

IEC Motors – a Brief Summary of Their Strengths

Increased efficiency
Instead of cast-aluminum rotors, copper technology is now used in the EFF1 motors. As a result, the motors have considerably smaller dimensions. The EFF2 and EFF1 motors are thus based on the same housing. When changing to the higher class of efficiency it is no longer necessary to redesign the machine, saving time and costs. Even more: with our EFF1 motors you can significantly save energy because they have up to 40% less power losses in comparison with EFF2 motors.

More power
With the same housing, our motors with increased output power offer higher kilowatts than standard power. And even better, we have also consistently pursued improved energy efficiency here. The motors are supplied in high efficiency and improved efficiency versions based on the CEMEP classification.

More flexibility
The optimized architecture of the motors generally facilitates installation. Encoders, brakes and external fans can be added with minimal effort. As an option, terminal boxes and feet can be freely mounted and attached. All motors can be run at up to 500 V either connected to the line or operated with inverter, without any additional steps.
