DC motors with integrated drives

The GR53 and GR63 motors from Dunkermotoren are cost-effective DC commutator motors with comprehensive digital electronic regulation and control.

These motors have digital control electronics for 4-quadrant drives built in. The electronic functionalities are provided by Dunkermotoren as firmware in the motor. In this way, precise speed control can be achieved with a minimum of wiring. As standard, the speed target input is provided by an analog voltage in the range 0 to +10 V. Two digital input signals determine whether rotation is to be clockwise or anti-clockwise, and can be used to block the controller and stop the motor with a holding moment. At a digital output, information is available about faults in the motor or electronics. In addition, there is an output which provides 16 impulses per revolution of the motor. An output signal for the direction of rotation is available as an option. For example, this permits monitored positioning of these compact DC motors with a minimum of external circuitry.

The GR53SI and GR63SI DC motors combine the advantages of conventional DC motors with those of modern digital control and regulation technology. Users in industrial and building automation, in medical technology and manufacturers of packaging and filling plant can benefit from these drives.

The GR53SI has an output of 40 W or 60 W at nominal voltages from 12 to 40 V and the output of the GR63SI is 50 W or 100 W. Depending on the version, nominal torque is up to 17 Ncm for the GR53SI and up to 29 Ncm for the GR63SI. The starting torque achieved is up to 140 Ncm or 210 Ncm respectively.
