Permanent magnet brushless dc motor controller permanent magnet brushless dc motor controller with ac induction motor stator permanent magnet multiphase winding multiphase winding rotor permanent magnet wire winding or cage windings rotor position sensor need not need not need electric spark without sliding contact, the EMC interference commutator and brush, EMC interference is strong, or there may be low collector ring EMC interference high-low audible noise low electronic controller must not required, you need to use when power DCDCAC using voltage range is wide, restricted by power device voltage is low, restricted by commutator pressure high mechanical properties close to linear linear nonlinear higher starting torque ratio is higher with low speed range is high, being limited by the rotor of the centrifugal force is low, restricted by commutator centrifugal force is high, being limited by the rotor of the centrifugal force of high efficiency and almost no loss is low, the rotor commutator and brush friction loss, brush pressure drop loss is low, the rotor moment of inertia of rotor is lesser, lossy corresponding fast big small power density is high, the stator winding is easy to heat dissipation is low, the stator winding is not easy heat dissipation with lower rotor torque ripple lossy fever higher controllability to poor life and reliability is higher, mainly is decided by bearing low, commutator brush the weak link in high security and high maintenance need not often maintenance needs regular cleaning or replacement brush need not often maintenance using low temperature range, restricted by permanent magnet is lower is higher
