Rinehart Motion Systems offers a host of services for OEMs, Systems Integrators and end users in several areas:
Power Circuit Design and Development
The company has considerable experience with the physical and electrical design of power circuits from a few Watts to 1000kW. This includes mechanical layout, thermal design, analysis of the losses and temperature rise of the components, laminated bus bar designs, DC link capacitor bank designs, and overall system enclosure design for a myriad of applications.
Novel and challenging end uses have included:
- An unmanned deep sea submersible propulsion control. This power hardware was rated at 20,000 feet below sea level, and operated at ambient (sea floor) pressure
- Hermetic, water cooled capacitor assembly for a 50kW drive
Traction Drives for EV, HEV and PHEV
RMS is developing traction controls (drives) for a variety of diverse alternative vehicles. The Company has significant activities on the Army's Future Combat Systems (FCS) Manned Ground Vehicle (MGV) platform.
Power Hybrid and Multi-Chip Module Packaging
All aspects of power module design are available. This include power substrate layout design, die attach tooling and fixturing, wirebonding layout design, gate and power leadframe design, injection molded component design, and comprehensive thermal analysis.
Applications have included:
