Abstract
A linear propulsion system and method of assembling and testing the same is disclosed. The linear propulsion system may comprise a track, a vehicle, a mover mounted to the vehicle, and a dual inverter system. The track may comprise a first plurality of stator sections interleaved with a second plurality of stator sections. The dual inverter system may include first and second multi-phase inverters that share input hardware.

A method of assembling and testing a linear propulsion system, the method comprising:
- providing a track, a vehicle, a mover, and a dual inverter system, the track including a first plurality of stator sections and a second plurality of stator sections, the second plurality of stator sections interleaved between the first plurality of stator sections, each stator section including a frame and a plurality of coils functionally mounted to the frame, each stator section having an activated state and a deactivated state, the mover mounted on the vehicle and disposed adjacent to the track, the mover including a plurality of magnets, the dual inverter system operably connected to each of the stator sections, the dual inverter system including a controller and first and second multi-phase inverters that share input hardware operably connected to each of the first and second multi-phase inverters, the first inverter operably connected to the first plurality of stator sections, the second inverter operably connected to the second plurality of stator sections;
- sharing input hardware by the first and second multi-phase inverters;
- receiving, by the first multi-phase inverter, power input from the common input hardware;
- receiving, by the second multi-phase inverter, power input from the common input hardware;
- sequencing, by the controller, the activation and deactivation signals to the first and second multi-phase inverters to activate a first stator section of the first plurality of stator sections followed by activating a second stator section of the second plurality of stator sections, the second stator section sequentially adjacent to the first stator section;
- and
- generating a propulsion force on the vehicle in a direction along the track when the first and second stator sections are activated;
- wherein, when power is received from the first multi-phase inverter, the first stator section of the first plurality of stator sections is activated but none of the second plurality of stators sections is activated.
