July 6, 2017 – Sensata Technologies announced the release of the Limited Angle Torque (LAT) Motor, BEI Kimco model LAT22-18, for motorized valve control. This direct drive motor can be integrated into a valve assembly for thermostat control as well as fuel metering, air intake shut off, fuel shut off, or air start control applications.
Measuring 2.2” in diameter by 1.8” in length, the motor features a coil assembly that is completely encapsulated to withstand the harsh chemical environment of the application.
The coil assembly also includes threaded mounting holes for installation into the valve assembly. The desired size and weight requirements were achieved by attaching permanent magnets directly to the butterfly valve shaft. The keys to the motor’s design are torque capabilities greater than 50 oz-in over an excursion angle of 90 degrees, operating temperature ranges from ambient to 257°F (125°C) and compact size.
In this valve control application, LAT technology was chosen over other solutions because the motor was designed to be used as a direct drive device. Direct drive motors eliminate gear boxes or other mechanical linkages that can break and wear. Additionally, because LATs are single phase, they are also simple to control and install.
