Gearless Lift Motor

EMF Motor has developed the world’s most efficient synchronous torque motor that offers high torque at low speed with precise motion control. The motors have a very large number of poles (66, 88) which provides rapid acceleration. The motors are highly dynamic, and are smooth and quiet in operation. The high number of poles, generated by an intelligent magnetic field, is effectively a magnetic gearbox, eliminating the need for a mechanical gearbox
 

These features perfectly suit the requirements of LIFT/ESCALATOR applications. Note that EMF Motor has a significant reference list of Lift installations (please contact us for more information)
All necessary certification available on request. See Documents)
Speed control is achieved using a Heidenhain ECN 1313 EnDat encoder.
Fitted with an A3 compatible DC safe brake, made by Mayr 
Owing to its high efficiency the motor remains cool
With the GREEN MOTION Smart Lift Energy Management System, the motor achieves an efficiency Class A (Report NL 13 EPCL P130100-01). The design includes a battery, which acts as an UPS, thus the lift can continue operating in the event of a mains power failure.
 

Patented design principle offers highest efficiency by far
Smooth start, stop and operation 
High lift riding comfort
Low vibration hence quiet operation (lowest torque ripple) 
Low moment of inertia means low starting current
Saves energy hence environmentally friendly
Motors stay cool
Constant torque over the speed range
High torque density and compact design
Reliable requiring little maintenance
