Figure 1 (top) illustrates the single-phase, R-134a capacitor start/capacitor run (CSCR) refrigeration compressor motor and starting relay circuit section of an electrical schematic diagram for the ...

RS and LS are motor winding resistance and inductance respectively. The two-phase winding currents are the outputs of the forward rotation function that drive the space vector PWM generator.

Phase paper was also used in this test and design. There were 36 slots in the motor’s design. Distributed winding was used by the motor, which resulted in a relatively complicated winding diagram. In ...

In the example shown, the motor-drive supply voltage is 5 V. Ohm’s Law is used to calculate total circuit resistance at 2.5 Ω to limit current through the winding to its 2-A maximum.

Figure 1: This diagram shows what a typical compressors windings would look like using an ohmmeter to check the windings. Each motor will have a different set of numbers, but the relationship of ...
