Three phase machine e.g. brushless direct current motor, for use in fan motor application, has stator including coil system provided as rotary field coil, where machine is designed as asynchronous machine with active squirrel-cage rotor
摘要
<p>The machine has a stator (20) including a coil system provided as a rotary field coil with tooth coils (2). The coils have a coil width corresponding to a groove division. The number of coils per groove (14) and strand is a whole number. The machine is designed as an asynchronous machine with an active squirrel-cage rotor. The rotor is designed as a short-circuit squirrel-cage rotor.</p>
