1. Motor shall come complete with a standard physical thermal protector built into the winding configuration. Thermal protector shall be resettable and have a protection setting NTE the thermal insulation class of the motor.
2. Over the entire speed range motor shall have comparable or better torque, watt consumption and current draw vs. incumbent.
3. With motor securely affixed in HALT chamber, it shall be able to withstand and operate as per design without any deleterious effects after being subjected to:
a. Temperature extremes of – 50C to 100C,
b. Thermal cycling at rates as high as 40C/min for 250 cycles. Temperature cycling is done typically within the operating limits of the motor. Where exceptions to the rule may apply Lennox Engineering may communicate this requirement during the design phase of the vendor qualification program.
c. Stepped random vibrations up to 30G rms
d. Combine thermal cycling and stepped random vibrations
