Brushless Motor

Maxon Precision Motors (Burlingame, CA) has introduced the EC-16 sterilizable brushless motor that has been assembled so that the coils are outside the rotor, providing good heat dissipation. Steam sterilization is specified at 273 °F at up to 2.3 bar for 20 minutes. The motor can be sterilized at least 100 times in an autoclave. The diameter is 0.63" with a length of 2.2". Continuous output power is 40 watts, while maximum speed is 50,000 RPM. Ambient temperature range is -4 to 275 °F, and maximum continuous torque is up to 1.78 oz-in, depending on the winding. The motor uses high-energy samarium cobalt magnets for a mechanical time constant of 5 ms. A sterilizable gearhead is available in 55 ratios ranging from 3.8:1 to 4592:1 with a maximum input speed of 8,000 RPM.

Analysis Software Used to Test Solar Car Steering and Stability

The Toronto, Canada-based Power of One solar car was built to set world distance records and promote the use of sustainable energy, unlike most solar cars that are built for racing. Most solar cars are designed only for controlled conditions on a track, but the Power of One project’s focus is practical solar technology that manufacturers can adapt into future mass-produced vehicles.

Ball Bearings

SKF USA (Kulpsville, PA) offers self-aligning ball bearings that allow for angular misalignment of the shaft relative to the housing without affecting operation. The ball bearings gain their self-aligning capability from a design incorporating two rows of balls with a common sphere raceway in the outer ring. They are available with cylindrical or tapered bores, in bore diameters ranging from 5 mm to 130 mm.
