3.1 Product description
The Pallet Drive is a completely enclosed electrical drive roller. It replaces external components such as motors and
gears, which require frequent maintenance.
The Pallet Drive can be operated in environments with heavy coarse and fine dust exposure.
The Pallet Drive is driven by an asynchronous three-phase induction motor. It is available in a single power stage only
and for most of the international supply voltages.
The Pallet Drive does not contain any oil and is not intended for continuous operation.
3.1.1 Options
Integrated thermal overload protection
A thermal circuit breaker integrated in the winding head protects against overheating. The switch trips if the motor
overheats. However, it has to be connected to a suitable external control device that interrupts the current supply to
the motor in case of overheating:
Integrated electromagnetic brake
The integrated electromagnetic brake can hold loads. It acts directly on the rotor shaft of the Pallet Drive and is
driven by a rectifier. The holding force of each Pallet Drive with brake corresponds to the belt pull of the motor. The
electromagnetic brake is available for all Pallet Drive:
3.2 Thermal protection
Under normal operating conditions, the thermal circuit breaker integrated in the stator winding is closed. When the
motor limit temperature is reached (overheating), the switch opens at a preset temperature to prevent damage to the
motor.
WARNING
The thermal circuit breaker is automatically reset after the motor has cooled off.
Inadvertent start-up of the motor
¾
Connect the thermal circuit breaker in series with a suitable relay or contactor so that the current supply to
the motor is safely interrupted when the switch trips.
¾
Ensure that the motor can be switched on again after overheating only with a confirmation button.
¾
After the switch has tripped, wait until the motor has cooled off, and ensure prior to switch-on that there is
no danger to persons.
