MCM abstract:

Micro-Coilless Motor (MCM) is invented based on the concept of ALS (refer below). It uses only a ring magnet (rotor), straight stator wires (no winding, coilless) and, combined with coreless as well as brushless concepts. MCM is classified under DC motor family: a brushless-coreless-coilless (windingless) motor.

MCM's major applications are micro-applications like for portable/micro devices of commercial appliances, aerospace, HVAC, military and medical equipments. MCM's design concept is also applicable to micro-generators which can be applicable for like speedometer for small radio levitating machines.

MCM is having several advantages over present motors:

™ Very compact; no winding, no core

™ Lighter; less material used

™ Higher efficiency; less loss (zero core loss, less copper loss)

™ Easy assembling; less parts

™ Shorter production lead-time

™ Lower cost production; less material, no winding machine investment
