Drive arrangement, especially for a lifting mechanism and/or a traveling drive |
摘要 |
The invention concerns a drive arrangement of a lifting gear and/or a traveling gear, with a pole-reversible rotary-current motor with windings for at least two different actuating speeds, with a pole switching element connecting the rotary-current motor to a voltage supply for changing between the actuating speeds of the rotary-current motor. In order to create a drive arrangement of a lifting gear and/or a traveling gear with a rotary-current motor, whose switching behavior is optimized in relation to the actuation of the rotary-current motor, it is proposed that a power switching element ( 3 ) be hooked up in front of the pole switching element ( 5 ), and it can be separated from the voltage supply via the power switching element ( 3 ) for the pole switching process of the rotary-current motor ( 2 ).
