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.

Mar 17 2019 My rotor of 3.5 in or the diameter of a common c.d. seem to work best with one or 2 downward pulling magnets and 3 machine nuts on the rotor to pick up extra energy Naturally bigger rotors will require more balance and likely more magnets but remember lightness and balance and the angle of the draw magnet are critical regardless of what size
Permanent magnets are used to provide a stationary magnetic field. Normally these magnets are positioned on the inner surface of the stator outside of the rotor. In order to create torque which makes the rotor spin the magnetic field of the rotor needs to continuously rotate so that it’s field attracts and repels the fixed field of the
An AC motor is an electric motor driven by an alternating current AC . The AC motor commonly consists of two basic parts an outside stator having coils supplied with alternating current to produce a rotating magnetic field and an inside rotor attached to the output shaft producing a second rotating magnetic field. The rotor magnetic field may be produced by permanent

High power dissipation will increase the copper wire temperature and the resistance as discussed in Note 11. Note 18 If the coil is driven by an AC driver such as the TS250 the RMS power dissipation is calculated using the user input peak current to calculate the RMS current and then calculate the RMS power.

Hence it is called squirrel cage. The two end caps i.e circular in shape are joined by rotor bars. These are acted based on the EMF i.e generated by the stator. This EMF is also generated outer housing that is made of laminated metal sheets and wire coiling. The two main parts of any type of induction motor are the stator and the rotor.
Nov 15 2014 The formula is n = 60 x f / p where n = synchronous speed f = supply frequency p = pairs of poles per phase. The actual running speed is the synchronous speed minus the slip speed. For a 50 Hz three phase supply 2 poles or 1 pair of poles = 3 000 RPM minus the slip speed = about 2 750 RPM or 6 7 n 4 poles or 2 pairs of poles = 1 500 RPM.
