ELECTRIC SERVO MOTOR EQUATIONS AND TIME CONSTANTS
The electrical resistance of a winding, at a specified temperature, is determined by the length, gauge and composition (i.e, copper, aluminum, etc.) of the wire used to construct the winding. The winding in the vast majority of industrial servomotors are constructed using film coated copper magnet wire. Based on the 1913 International Electrical

MEASURING MOTOR PARAMETERS - Control Technology …
support.controltechnologycorp.comFor a BLDC motor apply the ac voltage to one pair of the three wires. In both cases measure the voltage and the current. Remember that the BLDC motor is usually connected in WYE. Thus the readings will be line-to-line. You want the phase values for the voltage, so divide the voltage by 2. The impedance of the BLDC motor phase winding is then- [] []

With a constant rotor magnetic field produced by a permanent magnet on the rotor, the PMSM is very efficient when used in an appliance. In addition, its stator magnetic field is generated by sinusoidal dist ribution of windings. When compared to induction motors, a PMSM is powerful for its size.

You can concentrate this fi eld by winding the wire in which the electrons move into a tight coil with many turns. This causes many more electrons to be in motion in a small space, resulting in a stronger fi eld.
