Abstract
A direct drive robot motor may be used for the arms, legs, eyes and fingers of a robot. The motor comprises a rotor, having a permanent magnet, and a tubular arm portion, which is integral with the rotor and extends outwardly through a slot in a stator body. The stator body is wound with an aluminum coil and has a tubular extension to link it with the arm of another direct drive motor.
Claims28
A modular direct drive motor comprising
- a. a rotor having
- i. at least one permanent magnet;
- ii. a tubular portion which holds the permanent magnet;
- iii. an arm which extends perpendicularly outwardly from the tubular portion;
- and
- b. a stator having
- i. a body member with a casing wall;
- ii. at least one electromagnetic coil wound around the body member;
- iii. an opening in the casing wall;
- iv. a shaft means for rotatably connecting the stator to the rotor;
- and
- c. a first linkage means on the body member and a second linkage means on the arm for attaching the motor between two other motors with an arbitrary twist angle.
