M RUTTY & Co. has added a new solution that consists of a single quadrant speed controller “perfectly matched” to the brushless 3-phase BG motors by Dunkermotoren which has output power of up to 500 Watt. The combination is suited for use in battery powered applications (12/ 24V) or with low voltage supply.
The controller’s continuous output current is rated for 60 A with peak currents of up to 100 A (2 seconds) at a supply voltage of 8…30 V.
The parameter sets for ‘power stage off’, CW or CCW operation, two fixed speeds and variable speed operation can be selected either by dip switches or alternatively by digital inputs.
In addition, the motor speed can be set either by a 0-10 V, a 0-20 mA or a PWM input. The parameter sets can be configured via a USB interface.
A speed potentiometer scales the analogue input between 0-100 % or sets a fixed speed or current, respectively. Digital outputs provide motor and system information for external monitoring.
