The Moog Animatics Low Temperature Range (LTR) SmartMotor™ is available in a standard NEMA 17 frame size, model SM17205M-LTR (the “LTR-17”). This motor has been engineered for robust and reliable operation in extremely frigid environments and at high altitudes.[1] To achieve this, onboard internal heaters ensure that the motors can start up in temperatures below -40 degrees C. Along with this, other design changes allow these motors to withstand random vibrations up to 6 G RMS, 10 - 2000 Hz, and standard IP sealing protects the motors from condensation.[2] The LTR-17 motor allows you to have SmartMotor™ capability in a fully integrated, IP sealed package specifically designed for extremely low temperature and high altitude applications.
