Abstract: A rotor having a substantially cylindrical configuration for use in a brushless direct current electric motor having a high torque to size ratio. The rotor has an outer peripheral surface. The rotor also has a central rotor shaft and a first and second retaining ends mounted on the central rotor shaft and spaced from one another. The rotor also has a plurality of magnets configured to provide a magnetic flux with a stator disposed around the central rotor shaft. The magnets are radially disposed on the shaft and the rotor also has a sheath. The sheath is crimped around the radially disposed permanent magnets, and holds the magnets around the shaft. The sheath is lightweight and minimizes a gap between the permanent magnets and the stator to provide for an electromagnetic flux between the magnets and the stator windings, and for rotation of the central rotor shaft.

Abstract: An electric machine, such as a brushless direct current motor, includes a number of stator formed as stator sections. The stator sections are longitudinally offset from each other along a common central axis of the electric machine. The stator sections are magnetically independent of one another, but are electrically driven with offset phases typically in a manner similar to a standard multi-phase motor. The stator sections may be further offset with one another in radial position. The structure of the stator sections provides advantages in terms of efficiency, powe consumption, torque, and thermal performance, and can be especially advantageous where a battery is used to power the motor, such as in portable hand tools or driving motors for vehicles.
