Circuit for the auxiliary operating power systems of vehicles

In the auxiliary operating motors in vehicles, numerous varieties of motors have been used hitherto, namely single-phase series motors, direct current motors, single-phase and three-phase asynchronous motors. With a view to minimising the expenditure on maintenance, asynchronous motors are often preferred.

For systems with back-up ventilation, the voltage and frequency can be adapted and varied in accordance with the operating conditions. The supply of power to the transformer can be designed ...
