The present invention relates to a motor drive having a position indicator for actuation of an on-load tap changer or diverter. The invention proposes a motor drive for actuating an on-load tap changer or diverter. This diverter has a drive motor which drives at least one load gear and an indicator gear, wherein the load gear has a first drive shaft, having a first drive pulley which is mechanically connected thereto and is connected to the drive motor, and a second drive shaft having a second drive pulley which is connected thereto. The first and second drive pulleys are mechanically coupled, wherein the second drive shaft itself is operatively connected on the first side thereof to the on-load tap changer or the diverter and can be connected by the second side thereof to the indicator gear. The indicator gear co-operates with a position indicator, by means of which the currently activated position of the on-load tap changer or diverter can be displayed, and wherein a switchable coupling device can be provided between the position indicator and the load gear. |
