Gearboxes PLG/SG
Planetary gearboxes （PLG） have the highest continuous torque capacity of all types of gearbox; at the same time they have a very compact form, low weight, and excellent efficiency. Self-centering planet gears ensure a symmetrical force distribution. The ring gear also forms the housing of the gearbox. The gearbox output shaft is supported in two ball bearings so that it can withstand high axial and radial loads.
Worm gearboxes （SG） are noted for their very quiet running. The worm-gear shaft has bearings on both sides. The gear components, made of bronze or steel, and grease lubrication ensure a long service life at the rated torque. In many applications, the location of the output shaft at 90° to the motor shaft provides an optimum design solution. On request, worm-gearboxes can be supplied with a hollow output shaft.
Brakes
As standard, electrically-released brakes are supplied. Electrically-applied brakes are available on request. IP 54 covers are available for all brakes. Combinations of rotary encoders and brakes are possible. Depending on the motor-brake combination, degrees of protection up to IP 65 can be supplied.
Controllers
The controllers have been specially designed for optimum regulation of the speed, torque, and position of our dynamic motors.
Encoders
In order to satisfy all requirements for speed regulation and exact positioning, Dunkermotoren offers analogue tacho-generators （TG）, magnetic rotary encoders （ME/MG）, digital rotary encoders （RE） and absolute encoders.
