Press Release Summary:
The LMAA-04-01 Linear Induction Motor is suitable for applications such as conveying systems, baggage handling, theme park rides and active linear braking systems. The unit delivers a synchronous velocity of 4 m/s with 208 VAC 3-phase 60 Hz supply. The motor comes with 3-phase coil assembly that can be connected to AC line or to an adjustable frequency drive for variable speed control of the motor. The LMAA-04-01 motor can be dynamically braked or reversible and is offered in 43 mm x 76 mm x 221 mm dimensions.
Original Press Release:
Compact AC Linear Induction Motor
H2W 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]. The LIM measures 1.69” x 3.00” x 8.70” [43 mm x 76 mm x 221 mm]. 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 LIM is a non-contacting, high speed, linear motor that operates on the same principal as a rotary, squirrel cage, induction motor. They are 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. The motors are reversible and can also be dynamically braked.
The laminated coil assembly is used in conjunction with a customer supplied aluminum and steel reaction plate to produce a force. A customer supplied bearing system is required to maintain the .125" [3.0 mm] air gap between the coil assembly and the reaction plate. The width of the reaction plate equals the width of the LIM and the length is equal to the coil assembly length plus the stroke.
