New LMAA-04-01 Linear Induction Motor Generates 47 N at 15% Duty Cycle

Press Release Summary:

The LMAA-04-01 Linear Induction Motor is designed for high speed operation and is operated at zero speed to produce static thrust. The unit offers a synchronous velocity of 4 m/s with 208 VAC 3-phase 60 Hz supply. The motor is offered in 223 x 75 x 43 mm (L x W x H) dimensions and is suitable for applications such as baggage handling, theme park rides and conveying systems. It can be operated at 208 VAC 3-phase 60 Hz and is encapsulated using a 350°F potting compound.

Compact Linear Induction Motor

Santa Clarita, CA -- 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]. 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°] 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 x 3.0 in. [75 mm] wide x 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. 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 in. [3.0 mm] air gap between the coil assembly and the reaction plate. The length of the reaction plate is typically equal to the coil assembly length plus the stroke.

Advantages:

  • Only 2 Parts
  • Wide Speed Range
  • No Maintenance
  • Non-contact
  • Ease of Control and Installation

Typical LIM Applications:

  • Conveying Systems
  • Baggage Handling
  • Personal Rapid Transport Systems
  • Theme Park Rides
  • Active linear braking systems
