I've been trying to calculate the motor power of globe motor with gear box...
According to the manual, Globe motor with gear box have the following specs: No load speed = 87 RPM +- 1 Stall Torque = 150 in-lb If Motor power = ½ Free Speed X ½ Stall Torque and Free Speed in Rad/sec (1 RPM = 0.104 Rad/sec) Stall Torque in N-m (1 in-lbs = 0.11 N-m) Then the motor power = 1/2 * 9.05 Rad/s * 1/2 * 16.5 N-m = 37.33 Watt... But according to the motor presentation in white paper, Globe motor with gearbox have a motor power of 50W... Am I doing this wrong? Am I lacking some additional info to calculate the correct motor power? |
