Claim:
1. A system for driving a plurality of motors, comprising: a first permanent magnet synchronous motor coupled to a first slip coupling, wherein the first slip coupling comprises a first driver and a first follower, wherein the first permanent magnet synchronous motor is coupled to the first driver and the first follower is coupled to a first load bearing member; a second permanent magnet synchronous motor coupled to a second slip coupling, the second slip coupling comprises a second driver and a second follower wherein the second permanent magnet synchronous motor is coupled to the second driver and the second follower is coupled to the first load bearing member or a second load bearing member, and wherein the first load bearing member and the second load bearing member are in parallel to one another; and a bus connected to the first permanent magnet synchronous motor and the second permanent magnet synchronous motor, wherein the first permanent magnet synchronous motor and the second permanent magnet synchronous motor are electrically connected in parallel on the bus.
