But if we convert torque to newton-meters and speed to radians/sec then k will be equal to 1. This means that we can easily calculate the torque of your motor. Let's convert the speed to rad/sec first. 2750 RPM / 60 * 2 * Pi = 288 rad/sec. 250 W / 288 rad/sec = 0.868 Nm. 0.868 Nm = 7.68 in-lb.

NettetThe maximum speed of the HVH410 motor is only 6000 rpm but the power is compensated by the very high value of the torque. Electric motors torque and efficiency. The torque curves for both motors, at 400 V nominal voltage, are extracted from the pictures provided by the supplier (BorgWarner). NettetBy substituting equations 3. and 4. (torque and speed, section 2.1) into equation 2. (power, section 1.3 ), we see that the power curves for a D.C. motor with respect to both speed and torque are quadratics, as shown in equations 5. and 6. From these equations, we again find that maximum output power occurs at = ½, and = ½ repectively. scheels customer service chat https://cervidology.com
