System and method for controlling multiphase electric motors Patent uri icon

abstract

  • A multiphase electric motor for a down-hole electrical submersible pump having a rotor having a first set of rotor voids filled or partially filled with permanent magnetic material. The electric motor having a stator with three or more stator slots, three or more stator teeth and three or more coils. Individual ones of the three or more coils are wound about at least one of the individual ones of the three or more stator teeth, and positioned such that adjacent coils are non-overlapping or partially overlapping to form a fractional slot per pole per phase winding. The electric motor having a power supply configured to provide power to the three or more phase windings formed by series or parallel combination of the three or more coils and a controller configured to control transmission of power through the three or more windings.
