SL - ec - HEINZMANN - #3

HEINZMANN SL-EC motors are available in many other versions besides the ones presented here. They are built as servo drives or slow running motors with high torque in different variants. The series is produced with explosion-proof or high protection grade, with air or water cooling. The various types are available with a full or hollow shaft and as assembly kits for machine integration.

SL-EC motors are built very flat, especially the variant with a one-sided stator (SL-EC 11 B).

The advantages of the large air gap area of disc motors, coupled with the winding housed in iron packets, allow high torque and a powerful motor with high efficiency. In the variant SL-EC 22B this effect is further enhanced by the use of two stators and doubled magnets.

With their self-supporting magnets, SL-EC motors with two stators have a low inertial torque and are well suited for dynamic applications. In addition, they have a minimal detent torque.

Having replaced the mechanical commutator with electronic commutation, SL-EC motors are maintenance-free. Service-life is limited only by the bearings. Depending on dimensioning of the bearings, the motors allow up to 20,000 operating hours.
