2.1.2.2 Planetary gear LP
Fig. 2 Motor with planetary gearing LP (example)
Motors with a planetary gear LP have a block-type construction with a 1 or 2-stage
planetary gear ratio.
The gear unit has integrated thermal length compensation which compensates for the
linear expansion of the motor shaft on heating. The motor is mounted and the gear unit
centered on the motor by means of the bearing-mounted clamping hub and not with the
adapter plate. This eliminates radial strain on the motor. It is adapted to various motors
by means of the adaptor plate and spacing sleeve.
2.1.2.3 Planetary gear PLE
Fig. 3 Motor with planetary gearing PLE (example)
Motors with a planetary gear PLE have a block-type construction with a 1 to 3 stage
planetary gear ratio. They have been developed for applications which do not require an
extremely low circumferential backlash.
The gear units can be mounted in any position with out affecting the quantity of grease.
