Brushless motor 42 series

DCBLDC48 V

Product overview
The 42 mm brushless DC motor family offers multiple variants optimized for compact industrial applications. Representative top-rated values: rated torque up to 0.2 N·m and rated power up to 209.4 W (model 42ZWC75L-1). Star winding connection and Hall sensor feedback are standard. Gearbox and incremental encoder options are available.

Dimensional drawing
Dimensional drawings and circular/square flange views are provided per model. LT (body length) values correspond to the Motor characteristics table.

• Lead-out / wiring (UL3265 AWG26 for Hall signals): Yellow = Hall U (Hu), Green = Hall V (Hv), Blue = Hall W (Hw), Red = Hall Vcc, Black = Hall GND
• Lead-out / wiring (UL3265 AWG22 for phases): Yellow = U phase, Green = V phase, Blue = W phase

Torque performance curves
Torque, speed and power curves are available per model variant to support selection and integration (graphs provided for each representative model).
