In China, the power frequency is 50 Hz, the 2-pole synchronous speed is 3000rpm, the 4-pole synchronous speed is 1500rpm, the 6th-pole synchronous speed is 1000rpm, the 8th-pole synchronous speed is 750r/min. The winding comes and goes to form a loop, that is, the number of magnetic poles, which appears in pairs, and the poles mean magnetic poles. Answer: (b) 4 to 7 A/mm 2. 42. If the design of a 3-phase induction motor is done with a higher value of current density then. (a) weight of copper will be more. (b) temperature rise would be less. (c) copper losses would be more. (d) winding resistance would be less. -

The current in three phase winding generates magnetic field of constant magnitude that rotates if the currents are AC. The same could be done with two phase windings with 90 degrees appart, but we would need 4 wires, meanwhile the three phase system uses only 3 wires. Therefore the number of phases isn't related to the number of pole pairs. Transcribed image text: The stator of a 3 - phase, 10-pole induction motor possesses 120 slots. If a lap winding is used, calculate the following: (a) The total number of coils, (b) The number of coils per phase, (c) The number of coils per group, (d) The pole pitch, and (e) The coil pitch (expressed as a percentage of the pole pitch), if the coil width extends from slot 1 to slot 11. -

Motor windings can take many shapes or forms. However 3-phase distributed windings are the most commonly used in AC motors for industrial applications, which will be the focus of this article. The discussion which follows is equally applicable to the use of this type of winding in induction motors or in permanent magnet synchronous motors. Rotor Winding. In a motor, the rotating part is known as the rotor. The rotor includes the rotor winding as well as rotor core. The rotor winding is energized by the DC supply. The rotor can be classified into two types namely the phase wound and the squirrel cage. The squirrel cage rotor's core is made up of cylindrical iron core which has a. -

A single phase motor has a minimum of 2 poles. A 2 pole single phase motor has 2 poles and a synchronous speed of 3600 rpm. A 4 pole single phase motor has 4 poles and a synchronous speed of 1800 rpm (assuming 60 Hz). But in order to create initial torque to start the motor, the single phase motor must have another set of windings with lower. Mar 12, 2019 · 3-phase AC induction motors are comprised of the stator and rotor. During operation, a current is applied through the stator, which induces a magnetic field and leads to the rotation of the rotor. The rotational speed of the shaft and the applied torque are dependent on the operating frequency and the number of pole pairs in the motor’s windings..

The most common failure mode of a 3 phase AC motor is burnt winding or shorted winding leading to the damage of the motor. Often it is required to test the winding of the 3 phase windings with the aid of a multimeter or ohmmeter to determine whether the motor is still good or burnt or shorted. How to Test the Winding of a 3 phase Motor. The motor of claim 1 wherein the shared auxiliary winding comprises a 4-pole auxiliary winding phase shifted at least one slot less than a 90 degree shift with respect to the phase of the shared main winding when energized in the four pole configuration. 3.
