Due to increased demands on the rotational axis, direct drive rotary motors are now more than ever replacing conventional motor and gearbox rotary systems.
Elasticity and friction is eliminated with rotary motors because there are no components for it to accumulate. Backlash is also completely eliminated. The designer’s ability to create a more precise, dynamic, controllable rotary motion system is greatly simplified with the use of a rotary motor.
Slotted high-torque synchronous motors designed as internal and external rotors are characterized by efficient power generation, maximum power density, high acceleration capability and high speeds. These brushless power packs operate without wear and friction.
The motors of type RE are optimized concerning high torques. At same installation space the torque recovery is permanently higher compared to internal rotors. The cooling is at the inner side of the stator. The rotor is a drum with embedded permanent magnets. The magnet rails of the motors are designed and optimized accordingly to latest cognitions. The RE motors showing only less noticable cogging torques. Also the so called active torque ripples could be reduced down to amounts less than one percent.
Our high-speed series HSR and HSRV achieve even more, with more output and higher circumferential velocity due to their innovative winding structures. The circumferential velocity of these customized motors can reach up to 50 meters per second - the speed of an express train, with a mechanical release output of up to approximately 50 kW
