Abstract

The object of the invention is an arrangement in a direct connected drive in which the rotation speed of a motor connected to an actuator is controlled using a high frequency modulated frequency converter (4, 14, 16) supplying alternating frequency voltage to the motor stator. In the arrangement according to the invention, the motor stator has been fastened to the actuator frame and the motor rotor has been fastened to the rotating component of the actuator, bearing-mounted to the frame. The motor stator winding (18, 20) has been created as a two- branch winding, and the frequency converter is a dual-bridge inverter consisting of two essentially identical bridges (14, 16). The first bridge (14) supplies the first branch winding (18) of the stator, and the second bridge (16) supplies the second branch winding (20) of the stator. The first bridge (14) is controlled by the first control pulses (32) and the second bridge (16) is controlled with the second control pulses (38), which are simultaneous and inverse to the first control pulses.
