Please note: These are categorized as “high temperature” motors, they have a higher insulation class than standard motors and are intended to perform better at higher currents and higher ambient temperatures. Howeverrunning at or near full amperage in environments higher than 40Cwill impact longevity. We generally recommend for higher temperature environments to lower your amperage to increase the life of the motor.
