CONSTRUCTION OF POWER ASSISTING SYNCHRONOUS MOTOR
First Claim
1. A high power synchronous electric motor comprised of a rotor having a rotor shaft carrying a plurality of circumferentially spaced permanent magnets, a stator encircling said rotor and comprised of a plurality of poles around which coil windings are formed, a high capacity terminal circuit positioned at one axial end of said poles in circuit with said coil windings, a magnet detector positioned at the other axial end of said poles and cooperating with permanent magnets for determining the rotational position of said rotor, and a resinous body encasing said poles, said windings, and said high capacity terminal circuit to form a single unit.

Abstract
An improved synchronous electric motor incorporating a stator and large current terminal unit made into a single unit with solidified molding resin thus a separate casing is unnecessary and thus the constitution is simplified. The large current terminal unit and a magnetic pole position detector are located on opposite sides of the stator, with the former mounted on one end of the shaft of a cooperating rotor and with the other on the other end of the rotor shaft, and they are fixed in solidified molding resin to form a single body.
