Abstract
A driving device is provided with a gear unit and axial gap motors. The gear unit is provided with an input shaft and a driven member. The input shaft is supported by a supporting member. The input shaft is engaged with the driven member. Two axial gap motors are respectively attached to the input shaft so as to face each other.
Claims13
A driving device comprising a gear unit and axial gap motors, the gear unit comprising:
- an input shaft supported by a supporting member;
- a driven member engaged with the input shaft;
- and
- first and second axial gap motors attached to the input shaft so as to face each other wherein:
- the input shaft axially extends beyond both sides of the driven member,
- the first and second axial gap motors are both attached to one end of the input shaft between a first axial end of the input shaft and the driven member, and
- a brake is attached to a second axial end of the input shaft.
4 more elements
A device comprising:
- a first axial gap motor and a second axial gap motor, each motor having a rotor and a stator,
- a carrier,
- at least one crankshaft rotatably supported by the carrier and being connected to the rotors of the first and second axial gap motors;
- and
- at least one external gear engaged with the at least one crankshaft and being drivable thereby;
- wherein the first and second axial gap motors are attached to the at least one crankshaft so as to face each other,
- the first and second axial gap motors are disposed between the carrier and a first axial end of the crankshaft, and
- a brake is disposed on the second axial end of the crankshaft.
5 more elements
A driving device comprising:
- a plurality of input shafts supported by a supporting member;
- a driven member engaged with the input shafts, the input shafts each axially extending beyond both sides of the driven member;
- a plurality of first axial gap motors;
- and
- a plurality of second axial gap motors;
- wherein:
- each of the input shafts has one of the first axial gap motors and one of the second axial gap motors attached to one end of the input shaft between a first axial end of the input shaft and the driven member and such that the first axial gap motor faces the second axial gap motor, and
- a brake is attached to a second axial end of at least one of the input shafts.
