An electric motor contains two magnets; in this science project, you will use a permanent magnet (also called a fixed or static magnet) and a temporary magnet. Beginner Frog. Induction motor speed is a matter of poles and frequency - on 50 Hz you'll get 3000, 1500, 1000 as you go from 2-pole to 4 pole to 6 pole. (PK-M-2-6-P/S-BLK also include shim for opposite side of motor) Models: PK-J-2-6-P/S-BLK - For non-transom-mounted installations. But the fact of the matter is that a PWM VFD will drive a motor fairly well at all frequencies within practical limits. If the load on the motor is increased, the armature rotation slows and back EMF is reduced, since back EMF is proportional to speed. 3 phase induction motor. Gearbox below 3000rpm is always required for a 2 pole motor. The hybrid stepper motor is more expensive than the PM stepper motor but provides better performance with respect to step resolution, torque and speed. Axial Flux Induction Motor for Automotive Applications Hybrid and electric vehicle technology has seen rapid development in recent years. 6-pole motors operate at 1200 rpm (1000 rpm at 50 Hertz). The rotating armature (aka rotor) produces a back EMF, which opposes the armature voltage and reduces the armature current. Six-pole motors run at 1,200 rpm unloaded (7,200 Ã· 6) and between 1,050 and 1,175 rpm loaded. Products / 6 Pole. This is an analogue motor and while speed is accurate, the stepper motor would be better for working with computers since it functions on rigid "steps" of a turn. The 4 th pole in the switch is used in the control circuit. At 60 hz the four pole motor will have a synchronous speed of 30 revolutions per second, or more commonly known as 1800 revolutions per minute (rpm). The single phase induction motor resembles, three-phase, squirrel-cage motor except that, single phase induction. Motor torque changes with the speed. Test run the assembled motor with each set of 3 leads, and use a tachometer to determine the rpm. In addition to the torque of a cylindrical rotor, it can be expected that a salient pole rotor synchronous motor has a reluctance torque due to the saliency of the rotor as already discussed in Chapter 1.
