Brushless DC Motors & Matching Drives

EnduraMax 75s Series BLDC Motors

Brushless Motor

Allied Motion's EnduraMax 75s series are 75 mm (2.95 in) diameter integrated brushless DC motor-drives intended for unidirectional, open-loop speed control in commercial/industrial applications.

The EnduraMax 75s is ideal for mobile HVAC systems, liquid and gas pumps, fans and blowers, conveyors, and similar applications.

The cost-effective EnduraMax 75s is a compact, high power density integrated motor-drive that generates 40% more power than an equivalently sized DC brush motor. This coupled with it's quieter operation, longer life, and no need of brush maintenance makes the EnduraMax 75s the right choice to replace DC motors in equipment modernizations or new designs.

With rated winding voltages of 12 and 24 VDC, and continuous power output up to 228 W, EnduraMax 75s models are especially suited for battery-fed applications. They offer excellent performance, very long service life, and high reliability.

Options for the EnduraMax 75s include alternate speed control configurations, a wash-down version and alternate shaft configurations. As always with Allied Motion products, custom design versions are available to exactly match application requirements.
