Unit 08 Induction and Lenz`s Law
... Last week we saw that moving electric charges (currents) could produce a magnetic field, which we could “see” with a compass. The direction of this magnetic field was given by the right-hand-rule that we discussed. In that experiment we looked at the magnetic field produced by a straight wire, but w ...

A Design Study of Dual-Stator Permanent Magnet Brushless DC Motor
... 2. Design Method and Steps In Figure 1, the DSBLDC can be approximately treated as two BLDCs, i.e. the inner stator and the inside magnets compose an outer-rotor BLDC; the outer stator and the outside magnets compose an inner-rotor BLDC; both of the motors share the same rotor core. Due to the serie ...
