Specifications GNM 2145C
The GNM series stands for our DC servo motors with a permanent magnetic field. As voltage variants for the standard version we offer 12V, 24V and 42V. The nominal torque ranges in continuous operation S1 reach up to 1.6 Nm without gear box. Depending on the application, the motors can be designed with protection class IP21, IP41 or IP54. This series is particularly service-friendly due to carbon brush windows.
