Defining the Motor Requirements
Unless the gearbox is already designed, the actuator gearbox should be designed concurrent with the motor selection. This allows the overall system to be optimized. What being optimized means depends upon application. Optimal may mean lowest-cost, low size, or lowest … Continue reading
Motor size constants
Motor size constants are fixed by the amount of steel and copper in a motor. No matter how the winding area is filled, size constants remain fixed. The most important motor size constant is Km, the motor constant. It has units … Continue reading
Motor winding constants
Motor winding constants are changed by how the available copper space is wound. For example if you already have a motor datasheet and the motor has a back EMF constant of 10 V per kRPM then you could modify the … Continue reading
