Comer Industries has developed a new powertrain system for compact loaders.

The new system, which supports compact wheel loaders weighing up to 5 tons, includes a new electric module called the eMDI, which delivers power directly to the gearbox of the rigid compact axle. Within the gearbox, the rotational speed of the motor is reduced by a planetary drive unit and the rotary and torque motion is transferred to the front axle by a constant-velocity shaft.

Comer also showed off a planetary drive for electric excavators known as the WD300EX Series, an all-in-one integrated electric wheel drive designed for mini-excavators. The new planetary drive comprises a planetary gearbox and an interior permanent magnet motor. It is capable of delivering high torque to meet performance needs throughout the life of the machine.

The WD300EX is equipped with an electromagnetic negative brake that offers an electric, waterproof alternative to hydraulically-powered gearboxes, according to Comer.

Founded in 1970, Comer Industries is headquartered in Reggio Emilia, Italy. The company, which builds advanced engineering systems and mechatronic solutions for power transmission, has three divisions. Each division is devoted to a specific market segment: Agricultural Applications, Construction Equipment and Forestry, and Energy and Industrial.
