3.3 Functional description
The TW63B machine (B = generation) is only operated with IMB5 motors.
Machine with worm gear, anti-friction bearings, lubrication with synthetic gear oil for
traction elevators
3.3.1 Gear
The gear (gear drive) consists of a single-stage worm gear mounted on roller
bearings. The housing is in monoblock design with a bearing bracket integrated on
one side or on both sides and integrated dual-circuit brake. The worm gear toothing
runs in oil. The traction sheave is overhung.
3.3.2 Drive
Depending on the version, the drive comes from a three-phase motor standing (IMV1)
vertically on the gear or flange-connected horizontally (IMB5) on the gear to the worm
shaft, via worm wheel, traction sheave shaft to the traction sheave.
3.3.3 Drive motors
The drive motors are designed as device category IMB5 / V1 to accommodate the
motor. PTC thermistors are installed in the motor to provide protection against thermal
overloads.
3.3.4 Connection
The connection of the thermal motor monitoring and operational brake is located in
the motor terminal box.

.
In the case of drives for the machine room (TWR), a handwinding wheel is firmly
mounted
For deployment on non-controlled installations, a version with pole changing motor
(AC2 4/16-pin) with flywheel rim is available.
3.3.6 Coupling
Worm shaft and rotor shaft of the motor are connected by a flexible coupling. This
transfers the driving motion to the brake rotor of the disc brake.
3.3.7 Brake
The dual circuit shoe brake is spring actuated. Two independently acting brake shoes
press the brake lining onto the brake disc with spring force preset on the system.
The braking force is configured in such a way that one of the brake shoes is sufficient
to bring an elevator car loaded with full weight to a standstill.
