Angular Acceleration: 1,323·10³ rad/s²

Connection and Accessories:

Flex Print connector with 3-pole, 1mm pitch is recommended for connections.
Various accessories such as precision gearheads, lead screws, encoders, and cables are available.

Notes: For detailed technical data and lifetime performance, refer to the 'Technical Information' section. Specifications are subject to change without notice.

Catalog excerpts

Brushless DC-Servomotors2 Pole Technology, sensorless Series 0308 ... B Rated values for continuous operation Rated values are calculated with nominal voltage and at a 22°C ambient temperature. The Rh2 value has been reduced by 25%. Note: 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.
