	High Frequency (400 Hz) AC Induction Motors *for high performance applications (INM Series)*

The INM Series of high frequency AC induction motors is intended for aircraft applications utilizing 400 Hz power sources. Design features include both high efficiencies and high power densities to conserve weight. They are designed in accord with military standards, making them suitable for use on both commercial and military aircraft. INM motors provide a solution wherever there is a need for an induction motor to be powered from a 400 Hz power source. In addition, these induction AC motors also include custom features as requested by respective manufacturers.

Unique Features

High power density and efficiency
Flexibility of designs to suit custom needs
Contactorless detent torque magnet assemblies are optional, with little or no change in length
Multiphase design and run capabilities
Special housing configurations available as option
High Temperature operation capability; utilizing 220 ° C magnet wire as standard

Fields of Application

SL-MTI has a wealth of knowledge and experience designing AC Induction Motors in systems where DC was not available or where "off-the-shelf" AC motors would not fit the requirements. We highly recommend that you contact our engineering staff for any unusual application or requirements. SL-MTI has designed many of these types of induction AC motors for use in the following systems:

Actuation systems
Optical sight systems
Environmental control valves
Flight data instruments
Fire control and fuse applications
Fuel control valves
