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.

Now we shall consider the motor speed against an application. We need a motor such that higher limit of its permissible speed should be higher than the operating point of the application. Maximum permissible limit corresponds to upper limit of operating range diagram. This speed limit can be found in our catalogue.
