The patented EMF Motor® principle

German and Turkish co-production EMF Motor,
using the EMF Motor Principle, 
patented by European Patent Office
 has excellent torque and speed curve.
​

• The stator of the EMF Motor® is very similar to the conventional motor.
• Permanent magnets are glued to the rotor.
• When the motor is supplied with zero voltage and frequency, magnetic flux which magnetizes the motor, is formed.
• When the frequency is increased, the rotating field starts to turn.
• The two magnetic systems, permanent magnets and magnetization created by the rotating field, start to pull and push each other over the whole circumference.
• The direction of rotation of the rotor is opposite to the rotating field and the rotor turns much slowly than the rotating field.
• The permanent magnets and motor geometry define the speed reduction ratio.

• With this new motor principle a very high torque is created by low pole winding. The copper losses and hysteresis losses are very low which allows extremely high efficiency values.
• Due to the high number of magnetic poles, rotation is very slow and a high torque achieved. 
• In most cases, no additional blower or water cooling is required for these motors.
• The results show there is no other motor principle or design that even gets close to the level of efficiency achieved by SQM or the level of torque to weight ratio of the SQM design.
