Low-cost DC motors, designed as series-wound motors, shunt-wound motors or permanent-magnet motors form the basis for a wide range of combinations with helical, worm, double-worm and hollow-shaft gear units. The motors have preloaded ball bearings for especially quiet running, the gearbox housings are made of alloy and are available on request in countless design variants and with options such as holding brakes, tachometers, etc.
Inexpensive 1~ and 3~ AC motors, designed as Induction motors, shaded-pole motors, synchronous motors or AC commutator motors form the basis for a wide range of combinations with helical, worm, double worm and hollow shaft gear units.
