Danfoss' BMV Integrated Drive Motor is now available globally

Danfoss Power Solutions’ BMV Integrated Drive Motor, a two-speed axial piston motor with an integrated planetary reduction gearbox, are now available globally

The drive motor, previously available only in select markets, offers high durability and reliable performance in a compact, field-proven design. BMV is designed for dual-path tracked machinery such as compact track loaders.

With its smooth startup and high brake torque, the BMV Integrated Drive Motor has been designed to ensure reliable, predictable machine performance. The BMV motor can rotate smoothly, regardless of the pump swashplate angle at startup. This is made possible by a highly efficient rotating kit combined with an optimised gearbox system that provides high torque at low speeds and precise power transmission. The integrated design enables controlled, predictable machine startup, improving drivability, productivity, and overall machine performance. An integrated high-torque multiplate parking brake keeps the machine stationary, as the brake torque is higher than the motor’s maximum output torque.

The BMV Integrated Drive Motor has been designed to be compact and lightweight; its space-saving, integrated package allows simple installation, removal, and gear oil changes. Concave areas on the drive mounting flange enable direct access to the motor fasteners, allowing the BMV to be installed and serviced from the machine’s exterior. The BMV is also lighter in weight than other motors in its class, contributing to overall machine weight reduction. The BMV 28/32cc frame size is up to 14% lower in weight than similar motors, while the BMV 41/51cc size is up to 13% lower.

Designed for high-duty-cycle compact track loaders, the BMV Integrated Drive Motor can help to maximise durability and lifetime, featuring field-proven Danfoss rotating kits and optimised geometries for high performance and reliability, and a duo-cone mechanical seal prevents dirt ingress, reducing the risk of contamination. 

Fumiaki Egawa, global sales development manager, Daikin-Sauer-Danfoss, said, “Our BMV drive motor boasts a decade of experience, making it a product well proven in the marketplace. The time is right for expansion into additional markets, as tracked machines such as CTLs grow in popularity. Along with our Thorx CLM T motor, Danfoss can offer OEMs the track drive technology they prefer, axial piston with gearbox or cam lobe, delivering an ideal solution for a variety of machines.”

The BMV Integrated Drive Motor is available in two frame sizes and four displacements (28cc, 32cc, 41cc, and 51cc), with imperial and metric port configurations. Optional features include a loop-flushing valve and a Plus+1-compliant speed sensor. Suitable applications include crawler-type vehicles such as compact track loaders, crawler carriers/forwarders, crawler tractors, and crawler mowers.
