Often overlooked when sizing DC motors is the Speed-Torque Gradient.
The Speed-Torque Gradeint is defined as Δn / ΔM [rpm/mNm] .
The speed / torque gradient is an indicator of a motor’s performance. The smaller the value, the more powerful the motor and consequently the less motor speed varies with load variations. It is based on the quotient of ideal no-load speed and ideal stall torque.
The speed torque-gradient can be considered a measure of the motor strength, which is defined by motor type and size and not the winding selected. Basically it’s how much speed drop the motor will have for each 1mNm of torque applied.
In the figure below, enhancing the load torque leads to a linear reduction of the speed. Thus it becomes clear what the meaning of Δn/ΔM is: It’s the gradient of the speed-torque line.

Fast and easy with just a few parameters.
A new web tool by maxon motor, the leading provider of precision drives and systems, is now available at selection.maxonmotor.com. The “maxon selection program” (MSP) looks for appropriate drive systems that match the individual specifications of the user. In the simplest case scenario, the user only has to enter the supply voltage, the load speed and the load torque of the application.
The MSP is seamlessly integrated into the online catalog and e-shop of maxon motor, which contains 2700 products (brushed and brushless DC motors, gearheads, sensors, controllers). This means the user can select and order the suggested drive systems online from anywhere in the world, around the clock.
For drive specialists, the MSP provides an advanced search with additional parameters for specifying...
