An electric machine includes a stator and a rotor energizable by magnetic fields produced by the stator when receiving a stator current to produce relative motion between the rotor and the stator. A controller is configured to send the stator current through the stator at a current angle measured from the closest one of a pole of the rotor, determine a desired operational output of the electric machine, and determine a desired rotor motion corresponding to the desired operational output of the electric machine. The controller is further configured to calculate a vector control modulation applied to the stator that elicits the desired rotor motion, and adjust the current angle of the stator current based on the vector control modulation to cause the rotor to perform the desired rotor motion and achieve the desired operational output of the electric machine.

Power distribution within an electric machine

An electric machine includes a stator defining multiple stator poles with associated stator windings configured to receive a stator current. The electric machine also includes a rotor defining multiple fixed rotor poles with associated rotor windings, wherein the rotor defines a field energizable by magnetic fields produced by the stator windings when receiving the stator current to produce relative motion between the rotor and the stator and wherein the rotor is maintained in synchronicity with the magnetic fields produced by the stator during operation of the electric machine. The electric machine also includes a rectification system configured control against an alternating current being induced in the rotor poles as the field is energized by magnetic fields produced by the stator windings when receiving the stator current.

Power distribution within an electric machine with rectified rotor windings

A stator defines multiple stator poles with associated electrical windings. A rotor includes multiple rotor poles. The rotor is movable with respect to the stator and defines, together with the stator, a nominal gap between the stator poles and the rotor poles. The rotor poles includes a magnetically permeable pole material. The rotor also includes a series of frequency programmable flux channels (FPFCs). Each FPFC includes a conductive loop surrounding an associated rotor pole. The stator and the rotor are arranged such that the electrical windings in the stator induce an excitement current within at least one of the FPFCs during start-up.

A portable telephone shoulder rest comprising a base member formed of a flexible pouch filled with a weighted material, and a sleeve attached to the upper side of the flexible pouch. The sleeve is formed of elastic side panels interconnected by a flexible transparent perforated top panel. The lower portion of a portable telephone handset is received in the top end of the sleeve and extends through the open bottom end of the sleeve where the end of the handset rests in a depression formed in the flexible pouch. When inserted into the sleeve, the keypad of the handset underlies the flexible transparent top panel so that it may be viewed and actuated through the top panel. A non-slip surface may be applied to the upper side of the pouch to assist in securely retaining the handset within the sleeve. Also, a non-slip surface may be applied to the bottom surface of the pouch so that it securely rests on the shoulder of the user.
