Precious Metal Commutation Series 1228 ... SXR Values at 22°C and nominal voltage Nominal voltage Terminal resistance Rotor inductance Efficiency, max. No-load current, typ. No-load speed Stall torque Rotor inertia Friction torque Torque constant Speed constant Slope of n-M curve Thermal resistance: – winding to housing – housing to ambient (external plastic flange) – housing to ambient (external metal flange) Thermal time constant: – winding – housing (external plastic flange) – housing (external metal flange) Operating temperature range: – motor – winding, max. permissible Shaft bearings Shaft diameter Radial shaft load max.: – dynamic at 3 000 min-1 (3 mm from bearing) Axial shaft load max.: – dynamic at 3 000 min-1 – static (shaft unsupported) – static (shaft supported) Shaft play, max.: – radial – axial Speed up to Number of pole pairs Mass Housing material Magnet material Rated values for continuous operation Rated torque Rated current (thermal limit) Rated speed Note: ball bearings, preloaded 1,5 Rated values are calculated with nominal voltage and at a 22°C ambient temperature. The Rth2 p value has been reduced by 0%. The diagram indicates the recommended speed in relation to the available torque at the output shaft for a given ambient temperature of 22°C. 12 000 The diagram shows the motor in different conditions of thermal coupling, i.e. mounted 10 000 respectively on a plastic flange and a metal flange. 8 000 The nominal voltage (UN) curve shows, up to the thermal limit, the operating point at nominal voltage for the motor mounted on a plastic flange. Higher torque can be achieved by further reducing the thermal resistance. 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. Plastic flange Metal flange Intermittent operation Operating point at nominal value Recommended operation areas (example: nominal voltage 9V) For notes on technical data and lifetime performance refer to “Technical Information”.
