Induction motor no load max load rated load
WebMaximum efficiency is usually near 75% of rated load. Thus, a 10-horsepower (hp) motor has an acceptable load range of 5 to 10 hp; peak efficiency is at 7.5 hp. A motor ’s efficiency tends to decrease dramatically below about 50% load. Web11 jun. 2015 · Your desire to obtain the maximum load will be defined by your requirements and a specific speed. P (mech) = (Torque {rated} x speed {RPM}) / 9550. So if you are …
Induction motor no load max load rated load
Did you know?
WebService factor is the ratio of actual maximum power to the rated power mentioned on the plate of the motor. Example # 1: A 230 volt three phase, 1/2 HP induction motor has an efficiency rating of 88% and a power factor of 85%. Find the amp-load of the motor. Solution: I = (0.5 * 745.7)/(√3 *230 * 0.85 * 0.88) = 1.25 WebIf the no-load input active power of the induction machine is subtracted by its no-load winding loss, the result is the summation of the core and mechanical losses. The …

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.
