Abstract: A linear propulsion system (10) and method of assembling and testing the same is disclosed. The linear propulsion system (10) may comprise a track (30), a vehicle (14), a mover (44) mounted to the vehicle (14), and a dual inverter system (48). The track (30) may comprise a first plurality (36) of stator sections (45) interleaved with a second plurality (38) of stator sections (45). The dual inverter system (48) may include first and second multi-phase inverters (52a, 52b) that share input hardware (54).

Abstract: According to an aspect, an elevator system includes an elevator car 14 to travel in a hoistway 11 and a linear propulsion system 20 to impart force to the elevator car. The linear propulsion system includes a secondary portion 18 mounted to the elevator car and a primary portion 16 mounted in the hoistway. The primary portion includes a plurality of motor segments 26. The elevator system also includes a load sensor 52 operable to detect an elevator load on a brake. The elevator system further includes a control system 46 operable to apply an electrical current to at least one of the motor segments that overlaps the secondary portion, determine a measurement of the elevator load, and vary an electrical angle estimate while the brake is engaged and thrust is applied.
