Operating Area
Operating Area (2057S012B)
Recommended operation areas at nominal voltage 12 V

The diagram indicates the recommended speed in relation to the available torque at the output shaft for a given ambient temperature of 22°C.
The diagram shows the motor in a completely insulated as well as thermally coupled condition (Rth2 50% reduced).
The nominal voltage (UN) curve shows the operating point at nominal voltage in the insulated and thermally coupled condition. Any points of operation above the curve at nominal voltage will require a higher operating voltage. Any points below the nominal voltage curve will require less voltage.
