Stall torque MH [mNm] The torque developed by the motor at zero speed (locked rotor) and nominal voltage. This value may vary due to the magnet V type and temperature and the temperature of the 4,5 winding. Rotor inertia J [gcm2] The dynamic...

DC-Micromotors Technical Information Explanations on the performance diagram The performance diagram shows the range of possible operating points of a drive at an ambient temperature of 22 °C and includes both the operation in the thermally insulated and in the cooled state. The possible speed ranges are shown in dependence on the shaft torque. This section provides a very basic step-by-step procedure of how to select a DC-Micromotor for an application that requires continuous duty operation under constant load and ambient conditions. The example describes the calculations necessary to...

DC-Micromotors Technical Information Calculation of the main parameters In this application the available supply voltage is lower than the nominal voltage of the selected motor. The calculation under load therefore is made at 20 V. Calculation of the operating point at 20 V When the torque (M = 3 mNm) at the working point is taken into consideration I, n, P2 and η can be calculated: Current at the operating point inserting the values Supply voltage Terminal resistance No-load current Torque constant Output power at the operating point P2 = M · 2 π · n Efficiency at the operating point In...
