Homeowners and operators more and more search for equipment that improves productiveness. Skid steer loaders are prime examples. To select up heavier hundreds, full duties sooner, and improve journey pace, skid steers are being designed to ship greater energy and larger pressure. In the meantime, extra consideration is being paid to operator consolation. Clean, predictable operation is not a want – it’s a requirement.
Excessive-pressure hydraulic pumps are delivering the ability skid steers want, and the market is shifting to cam lobe motors to enhance the efficiency of those pumps. Cam lobe motors provide greater strain scores and larger effectivity than different applied sciences, delivering 30% extra pressure. Nevertheless, cam lobe motors have traditionally fallen brief in the case of two-speed shifting, bundle measurement, and effectivity all through the pace vary.
Two-speed motors assist the trade drive for larger productiveness, delivering greater torque when working and better pace when roading. However an issue arises when shifting between the 2. A sudden change within the wheel pace or torque can create a jarring shock response, leading to machine instability and even a misplaced load. The impact is worse when the machine is chilly. Shocks could be erratic or delayed, undermining driver confidence.
With motors positioned back-to-back in skid steer loaders, size can be vital. Typical cam lobe motors have a big envelope, which might make meeting and repair a problem in compact machines.
Lastly, beginning effectivity and most pace effectivity generally is a drawback for cam lobe motors. When a machine is stationary, torque effectivity is low, making a weak point in machine efficiency. Additionally, the warmth generated at most pace makes the machine scorching and wastes vitality on cooling.
Danfoss Energy Options’ new Thorx line of cam lobe motors solves these challenges. The CLM 8 S and CLM 4 S cam lobe motors — designed particularly for development equipment with chain drives, reminiscent of skid steer loaders — are actually accessible. Fashions for different drive sorts are coming quickly.
Danfoss Thorx motors function newly developed two-speed know-how, which reduces shock at pace changeover by 70% and eliminates inconsistencies as a consequence of temperature, leading to smoother, extra predictable machine dealing with.
Thorx motors function a bigger diameter rotary group that permits the parking brake to be built-in within the middle, slightly than bolted to the rear. This configuration makes the motors 33% shorter in size than different chain drive motors, with solely a one-centimeter improve in width. Decreasing the motor’s house declare simplifies set up and frees OEMs to extend the scale of the chains driving the wheels, which might improve the lifetime of the machine.
The elevated house created by the bigger rotary group permits a return to confirmed multidisc brake know-how, which gives robust parking torque in addition to clean emergency stopping. Not like canine clutch brakes, which produce harsh emergency stops and put on out extraordinarily rapidly — typically in as few as one or two stops — the Thorx motor’s brake is designed to face up to at the very least 100 dynamic emergency stops.
One other benefit of the motor’s bigger rotary group is decreased friction and stream losses, which will increase the beginning effectivity in addition to high-speed effectivity by 5%. Operators can obtain sooner journey speeds or use much less energy on the similar pace whereas losing much less vitality within the type of warmth.
Danfoss Thorx motors have reinvented cam lobe know-how, eliminating shortcomings whereas sustaining the know-how’s robust factors. All motor applied sciences have their place, and with its full motor portfolio, Danfoss has the correct know-how for the appliance, making certain an ideal match.
