Officially, in addition to the Brochure details There is almost no data available on the rated power and torque of the electric motors. Only the label attached to the hub motors sometimes provides additional information.
Simulation tool
Grin Technologies offers a simulation tool on its website. Here you can you can select the TDCM (Stromer motor) and various other components and simulate the motor characteristics for the set values.
The TDCM DD (Direct Drive) was calculated using the example of an ST3.
Here a comparative simulation with different system weights and the TDMC IGH 395 rpm motor.
Motor temperature development
Furthermore, the motor temperature development can also be simulated with corresponding characteristic data (nominal voltage, max. battery current, gradient, etc.). Here to go to the "trip-simulator" tool.
Power, torque, peak power, rated power and co. explained
You can also find out more about the marketing value of peak engine performance or the difference between torque and power at GRIN. here inform. Grin also describes the 'mumbo-jumbo' with the declaration of peak performance that various e-bike manufacturers engage in.
