Abstract
A drive unit for power control of electric motors comprises a circuit board ( ) with surface leads and a number of logic components as well as power controlling semi-conductors ( ), and two or more power distribution bars ( ) which extend along the circuit board ( ) and are connected to a power source and/or one or more motor connections. Each of the power distribution bars ( ) is a sheet metal stamping formed with a number of integral connector pins ( ) which are to be received in a number of apertures ( ) in the circuit board ( ) and rigidly connected to the surface leads for communication with the semi-conductors ( ). Each one of the power distribution bars ( ) is stamped from a flexible thin sheet metal and is folded along a longitudinal line ( ) into two parallel sections ( ). The connector pins ( ) extend from a first one ( ) of the two sections ( ). Each one of the connector pins ( ) is substantially Z-shaped for providing an increased flexibility and for forming together with a second one ( ) of the two sections ( ) a fixing device for a ferrite ring element ( ).
