Brushless motor C12B-03

8 Vfor roboticsfor measurement instruments

Overview
The C12B series comprises small-diameter brushless motors with an outer diameter of φ12 mm. Multiple sub-models are available with differing lengths, nominal voltages, terminal resistances, no-load speeds, currents, startup torques, efficiencies and output powers. The datasheet below lists electrical and mechanical performance for each sub-model to support selection for precision industrial applications such as micro-actuators, instrumentation, robotics and compact automation systems.
