Compact Linear Induction Motor

H2W Technologies (Santa Clarita, CA) engineers have developed a compact Linear Induction Motor (LMAA-04-01) that can generate 10.6 lbs [47 N] at a 15% duty cycle. Operating at 208 VAC 3-phase 60 Hz, the synchronous velocity of this LIM is 160 in/sec [4 m/s]. This LIM was designed for high speed operation; however, it can also be operated at stall (zero speed) to produce static thrust. This motor is encapsulated using high temperature 350°F [176°C] potting compound which protects the components and seals it from moisture.

A non-contacting, high-speed, linear motor measuring just 8.7 in. [223 mm] long × 3.0 in. [75 mm] wide × 1.7 in. [43 mm] high, this LIM operates on the same principal as a rotary, squirrel cage, induction motor. They are typically used in applications that do not require positioning. The 3-phase coil assembly can be directly connected to the AC line for single speed applications or to an adjustable frequency drive for variable speed control of the motor.
