Overload protection in the ECR 2 26W motor

The ECR2 26W motor is designed to continue operating even under overload situations thanks to integrated protection features.

When an overload is identified, the ECR2 26W motor does not cease operation. Instead, it adjusts the set speed of the motor until the torque, power, or temperature fall within acceptable boundaries. This adjustment is achieved as follows:

Protection mechanism Criteria Behaviour function
Locked rotor The rotor is locked. Motor will attempt to restart every 10 seconds until the blockage is 
removed.
Torque constraint Required torque exceeds 0.14Nm 
and set speeds less than 1800rpm.		 Motor speed will reduce until torque equals 0.14Nm.
Power constraint  Required power output higher than 
26W.		 Motor Speed will reduce until power equals 26W.
Speed constraint The maximum speed is 2300 rpm. The motor speed cannot exceed 2300rpm.
Temperature constraint Internal motor temperature exceeds thermal limit. At full power (26W) or full torque (0.14Nm), the thermal limit will activate at roughly 45°C external ambient. Motor speed will reduce until internal 
temperature is below the limit.
