Essence of Pole Pairs
The term "pole pairs" in a resolver denotes the number of magnetic poles present in each phase. This seemingly simple attribute is crucial, as it directly impacts the resolver's output voltage and current—key parameters in its design and operation. The number of pole pairs essentially dictates the resolver's speed, with a higher count correlating to increased output voltage. Moreover, it also bears on the physical dimensions, weight, and cost of the resolver.
Selecting the Right Pole Pairs
The selection process begins with understanding the specific requirements of the application. Generally, a higher number of pole pairs is preferred when a higher output voltage is needed, while a lower count is chosen for applications requiring higher output current. However, this choice is not made in isolation.
Power System Characteristics: For larger power systems, a higher number of pole pairs can help reduce harmonic currents, whereas smaller systems might benefit from a lower count to minimize electromagnetic interference.
Load Characteristics: The variability of the load also plays a role. A large load variation range may necessitate a higher number of pole pairs to maintain output voltage stability, while a smaller variation range could allow for a lower count to reduce the resolver's physical footprint.
Influencing Factors
Several factors can sway the decision on the number of pole pairs:
Power Supply Voltage: Fluctuations in the supply voltage can affect the resolver's output. A higher number of pole pairs may be selected to ensure voltage stability in the face of significant voltage changes.
Load Variation Range: A substantial range in load variation calls for a higher number of pole pairs to maintain voltage stability, while a more consistent load might permit a lower count.
Resolver Design Parameters: Parameters such as the resolver's speed and the number of coil turns also influence the selection, as they directly affect the output voltage and current.
