The thermal data given in our catalogue may be indicative, and it should always be confirmed whether the heat dissipation in a given application is actually better and stable. As per the speed-torque curve in Portescap’s catalogue, there is a temporary working range in which we can overload the motor for a small time span. However we should always confirm what that time span should be, and it all really depends on motor size and design. There is a definite time span for every motor size, and this limitation comes from the coil temperature and more precisely, how fast the motor coil or winding heats up.
