Brushless permanent magnet ring motor, 14-inch diameter, 60 kW

ThinGap 14050 Ring Motor was developed under DARPA contract using patented ThinGap technology. The 14-inch diameter dc motor produces up to 60 kW, with smooth torque and speed because the design produces no rotor-to-stator magnetic forces, no cogging, no eddy current losses, and no hysteresis, company said. It has stainless steel rotor and up to 10,000 rpm.

The dc motor produces up to 60 kW (80.4 hp), with smooth torque and speed because the design produces no rotor-to-stator magnetic forces, no cogging, no eddy current losses, and no hysteresis. The 13-4 PH stainless steel rotor and magnets mounted inside the outer face of the ring allows for high revolutions per minute operations, up to 10,000 rpm.

The brushless permanent magnet ring motor design (13.56-in outer diameter and 6-in length) allows wide flexibility for integration, suggested Matt Cheresh, ThinGap vice president of sales and marketing. “Fan blades can be mounted inside the circumference of the rooter for high-speed operation, or across/outside the rotor for lower speed operation. With inside fan blades, 400 to 600 pounds of thrust can be generated, depending on the fan design and temperature requirements,” Cheresh said.

A laminated, precision-etched copper sheet results in a very thin, 0.15-in. wall stator. Airflow on both sides of the coil and lack of eddy current losses provide excellent cooling. Also, the company says, because the motor will not saturate magnetically, higher torque can be achieved.
