With a 60 cycle power supply the synchronous speeds available are 3600 RPM, 1800 RPM, 1200 RPM and 900 RPM. Induction motors develop their torque by operating at a speed which is slightly less than synchronous speed. Typically they will,How to determine the pole number of an induction motor,,For a four pole machine, 60 x 50 / 2 = 1500 rpm so the same size motor at 5.5kW, 400v but 4 poles will have a nominal speed of 1500rpm but will run near 1455 rpm. When selecting a three phase motor, the number of poles is chosen to achieve the speed of rotation that you require. Here are two tables, one for a 50 Hz power supply and one for a 60 Hz power supply: The formula is n = 60 x f /p,

## Small Jaw Crusher - 911Metallurgist

The 911MPEJAC23 is a Small Jaw Crusher of 2.25" X 3" manufactured to easily crush any rock from 2" (50mm) down to a D50 of 700 micron (28 Mesh) which also correspond to a crushed discharge P80 size of 80% passing 1400 microns or 14 mesh. The discharge opening (closed-side-setting) of this 55 mm X 75 mm "big-small crusher" you can adjusted with a wrench. With a short throw at a quick 525 RPM,Motor Poles & RPM — TW Controls,So, for example, if you have a 4 pole motor on 60 Hz then RPM=60*(2/4)*60=1800 rpm. 60Hz is the most common frequency in the US. 50Hz is the most common frequency outside the US.

## Pump RPM to achieve flow - Pump engineering - Eng-Tips

25/10/2012· For 60 Hz supply, a 10 pole motor has a synchronized speed of 720 RPM only. Therefore you have to use a 8 pole motor which has a synchronised speed of 900 RPM. Actual RPM will be less to to slip. At 900 RPM the pump will give about 35 ft head at 3750 GPM or about 5700 GPM at 20ft head.what is electric bike motor power torque speed efficiency,Power (hp)=[ Motor Speed(rpm) × Torque (lb-ft) ] ÷ 5252. 1 hp = 746 watts = 0.746 KW. 1 lb-ft = 1.356 Nm [Also, Power(W)= U × I = I 2 × R] Rated Voltage (V): A specific voltage level that motors are designed to yield optimal performance when operating at. Generally, motors are designed with a 10% tolerance for voltage above and below the rated value due to changing load conditions. Torque,,
