Brushed DC Motors
|Applied Voltage||12 / 24 / 40 / 48 / 60||VDC|
|Nominal power||3 - 796||W|
|Nominal torque||0,01 - 0,67||Nm|
|Nominal speed||2500 - 4000||rpm|
Each of our brushed DC motors can be operated in both clockwise and counter clockwise rotation with regard to the direction of rotation. The mechanical commutation via a multi-part collector ensures a long service life for the motors.
You will find a detailed comparison of our brushed DC motors in terms of size, length, output power, voltage, speed, torque and the components used, such as encoders, brakes or planetary gearboxes, on page 10 in our main catalogue.
How does the connection resistance behave with the brushed GR motor?The connection resistance results from the nominal voltage/starting current.
Can the motor be operated at a voltage other than the nominal DC voltage? How does the characteristic diagram change if the supply voltage is not equal to the rated voltage?Yes, the motor can also be operated with different voltages. For motors with integrated electronics, the permissible limits of the electronic components must be observed.
Motors from Dunkermotoren are usually designed for a standard industrial rated speed in the range of 3000 to 4000 rpm. If an application requires it, the speed can be easily adapted to the desired operating point by selecting a different winding.
Example: When using a GR motor with nominal 12 V at a supply voltage of 24 V, the no-load speed doubles and the entire motor characteristic curve shifts parallel accordingly. This results in a significantly increased continuous output power of the motor.
How does Dunkermotoren specify the motor power?The nominal power P(N) is the output power of the motor which can be generated permanently, calculated from nominal speed and nominal torque. The motors from Dunkermotoren are always measured according to EN60034 in thermally insulated condition. The measurement methods for the specification of motors are not standardized and sometimes differ significantly between the different suppliers. This makes it difficult to compare values even with comparable motor concepts and speeds.
