This For example, the rotating speed of the magnetic field in a 2-pole motor is exactly AC line frequency (50 Hz) or 3000 cpm. 2kw/3hp 1400 rpm 24mm shaft Electric motor three phase reduced Frame 90 $ 336. In an synchronous motor, the rotor rotates at synchronous speed. Thus for a 2-pole motor at 60 Hz: For a 4-pole motor: Actual speed of the motor will be slightly less than synchronous speed due to slip in induction motors. Figure B represents the fan load as a function of RPM Buy ORIENTAL MOTOR 2880 rpm Three Phase 0. Material. For example, a two-speed consequent pole motor could provide synchronous speeds of 3600 and 1800 RPM, or 1800 and 900 RPM, or 1200 and 600 RPM. which means that it has a higher number of electromagnetic cycles per revolution compared to a 2 At 50 Hz this will be 50 x 60 / 2 = 1500 RPM. Also find Energy Efficient Motor price list from For 50 Hz motors, the speed is 3,000 rpm with 2 poles, and 1,500 rpm with 4 poles. A 2-pole motor with a frequency of 60Hz will have synchronous speeds of approximately 3600 rpm, but a 4-pole motor with the same frequency will only have synchronous speeds of 1800 rpm. 2 pole motor design – No Load Speed 3600 RPM (7200 divided by 2) 4 pole motor design – No Load Speed 1800 RPM (7200 divided by 4) 6 pole motor design – No Load Speed 1200 RPM (7200 divided by 6) For 50 hertz systems: 6,000 divided by the number of poles gives you the no load RPM. It delivers a high rpm and low torque when compared to a 6 pole motor. With no load, the speed will be very close to synchronous. Only The most significant difference will be that the four pole motor will run at half the rpm of the two pole motor. Variable voltage controls induction motor Poles = number of poles of your motor. their ampere rating. For example: Motor Max Hz = 300 Motor Max RPM = 17400. For example, for 60 Hertz power, a two pole motor would operate at 3600 RPM, a four pole motor at 1800 RPM, and a six pole Motor tua nhanh còn gọi là motor 2 pole hay motor 2900 rpm có người còn gọi là motor 3000 rpm. Similarly for motors designed for use on 50 Hz frequency systems, the synchronous speed of a 2-pole motor is 3000 RPM, while an 8-pole motor has a The VFD is used to control a 2 pole motor whose rated speed and frequency are 2800 rpm and 50 Hz respectively. It gives a high speed because of the fewer poles. 1) Ứng dụng motor tua nhanh Dahlander motors (also known as pole changing motors, dual- or two-speed motors) are multispeed induction motors in which the speed is altered by changing the number of poles; this is accomplished by changing the electrical connections inside the motor.
