Mechanical Time Constant: 5 ms.

Operational Guidelines:

The motors are designed for both continuous and intermittent operation, with specific recommendations for speed and torque based on ambient temperature conditions.
Diagrams provided indicate the relationship between speed and torque at nominal voltage, highlighting areas for optimal performance.

Options and Accessories:

Various gearhead and encoder combinations are available, such as the HEM3 and PA2-100 encoders.
Extended temperature range and additional shaft options are offered.

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

Catalog excerpts

FAULHABERDC-Micromotors Precious Metal Commutation Rated values are calculated with nominal voltage and at a 22°C ambient temperature. The Rh2 value has been reduced by 0%. 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.
