1

Salient pole

Uses only attractive magnetic force

Non-salient pole

Uses both attractive and repulsive forces

Motor Types

IM

Induction machine/motor, inverter driven

RSM

Reluctance synchronous machine, inverter driven

PMSM

Permanent magnet synchronous machines

Switched Reluctance Motor

This may be the one to build. Simple construction, rotor is just made of low carbon steel.

There's a lot of questions about how to construct and drive them:

• best material for rotor (low carbon steel, but what kind)
• best material for stator (ferrite?, steel?)
• hall sensor vs back EMF vs optical encoder

How does hysteresis play into this? What does the flux look like in the rotor? Eddy currents?
