House owners and operators more and more search for equipment that improves productiveness. Skid steer loaders are prime examples. To choose up heavier hundreds, full duties quicker, and improve journey pace, skid steers are being designed to ship greater energy and larger power. In the meantime, extra consideration is being paid to operator consolation. Clean, predictable operation is now not a want – it’s a requirement.
Excessive-pressure hydraulic pumps are delivering the facility skid steers want, and the market is shifting to cam lobe motors to enrich the efficiency of those pumps. Cam lobe motors supply greater stress scores and larger effectivity than different applied sciences, delivering 30% extra power. Nevertheless, cam lobe motors have traditionally fallen quick with regards to two-speed shifting, package deal dimension, 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 might be erratic or delayed, undermining driver confidence.
With motors positioned back-to-back in skid steer loaders, size can also be vital. Typical cam lobe motors have a big envelope, which may make meeting and repair a problem in compact machines.
Lastly, beginning effectivity and most pace effectivity could be a downside 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 sizzling and wastes power 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 building equipment with chain drives, equivalent to skid steer loaders, are actually obtainable. Fashions for different drive varieties are coming quickly.
Danfoss Thorx motors characteristic newly developed two-speed expertise which reduces shock at pace changeover by 70% and eliminates inconsistencies as a result of temperature, leading to smoother, extra predictable machine dealing with.
Thorx motors characteristic a bigger diameter rotary group that allows the parking brake to be built-in within the heart, moderately 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 may improve the lifetime of the machine.
The elevated house created by the bigger rotary group allows a return to confirmed multidisc brake expertise, which affords sturdy parking torque in addition to easy emergency stopping. Not like canine clutch brakes, which produce harsh emergency stops and put on out extraordinarily shortly — typically in as few as one or two stops — the Thorx motor’s brake is designed to resist a minimum of 100 dynamic emergency stops.
One other benefit of the motor’s bigger rotary group is diminished friction and stream losses, which will increase the beginning effectivity in addition to high-speed effectivity by 5%. Operators can obtain quicker journey speeds or use much less energy on the similar pace whereas losing much less power within the type of warmth.
Danfoss Thorx motors have reinvented cam lobe expertise, eliminating shortcomings whereas sustaining the expertise’s sturdy factors. All motor applied sciences have their place, and with its full motor portfolio, Danfoss has the proper expertise for the appliance, guaranteeing an ideal match.
