The compressor uses capacitors to smooth ripples in the PC link in the motor drive. Instantaneously after a power failure, the motor becomes a "generator," using its angular momentum to create electricity (sometimes known as back EMF) and keeping the capacitors charged during the brief coastdown period. The capacitors, in turn, provide enough power to maintain levitation during coastdown, allowing the motor rotor to stop and delevitate. This feature allows the compressor to see a power outage as a normal shutdown.OIL-FREE DESIGNOil management, particularly as it pertains to the lubrication of compressor bearings, is a critical issue in refrigeration-system design. But with magnetic bearings, this issue is avoided. Only a very small amount of oil is required to lubricate other system components, such as seals and valves; often, however, experience shows that even this small amount of oil is not needed. Avoiding oil-management systems means avoiding the capital cost of oil pumps, sumps, heaters, coolers, and oil separators, as well as the labor and time required to perform oil-related services. Reports indicate that for many installations, compressor-maintenance costs have been cut by more than 50 percent.

The EFI system contains an electronic control unit that can monitor the equipment''s functions, including dash displays (engine temperature, speed hours); analog/digital inputs (vehicle incline sensor, safety interlocks, vehicle and/or blade speed); diagnostics (air cleaner status, oil change intervals, operator safety warnings); and electronic governor/throttle controls (ground speed control, cut height ''control).The 725 cc Command Pro 26 EFI produces 41.6 lb.ft. torque at 2200 rpm, has a compression ratio of 9:1 and utilizes Kohler''s nickel-silicon plated Power-Bore cylinders for longer cylinder life.
