WebIn the area to the right of the maximum torque on the characteristic curve, increase in the load does not so much reduce the speed of low-impedance motors. The torque … WebGiven that, we can see that efficiency for every motor is going to be 0% at no load (i.e., maximum speed at 0 torque). Efficiency will then increase as torque increases until it reaches a maximum and then it will start to drop off until stall torque is reached. At this point, the efficiency is 0% again because the speed will be zero.
Web16 dec. 2024 · The nearest speed that satisfies the synchronous speed formula at 50 Hz is 1500 (1500 = 120 X 50 / 4), so this is a 4-pole motor. Since the rated speed is given as 1475 RPM, we know that the slip at rated load is 1500 - 1475 = 25 RPM. Horsepower = Torque (Lbs - Ft) X RPM / 5252, so the rated torque is 214 Lbs. - Ft. Web30 aug. 2024 · Capacitive load is similar to that of inductive load. In capacitive loads also, current & voltage are out of phase with each other. The only difference is that, in capacitive load current leads the voltage …
