Homeowners and operators more and more search for equipment that improves productiveness. Skid steer loaders are prime examples. To choose up heavier masses, full duties sooner, and enhance journey pace, skid steers are being designed to ship increased energy and better drive. 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 ability skid steers want, and the market is shifting to cam lobe motors to enrich the efficiency of those pumps. Cam lobe motors supply increased stress scores and better effectivity than different applied sciences, delivering 30% extra drive. Nonetheless, cam lobe motors have traditionally fallen quick in the case of two-speed shifting, package deal measurement, and effectivity all through the pace vary.
Two-speed motors help the business drive for better productiveness, delivering increased 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 may be erratic or delayed, undermining driver confidence.
With motors positioned back-to-back in skid steer loaders, size can be essential. 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 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 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 development equipment with chain drives, similar to skid steer loaders, at the moment are out there. Fashions for different drive varieties are coming quickly.
Danfoss Thorx motors function newly developed two-speed know-how which reduces shock at pace changeover by 70% and eliminates inconsistencies resulting from temperature, leading to smoother, extra predictable machine dealing with.
Thorx motors function a bigger diameter rotary group that allows the parking brake to be built-in within the heart, quite than bolted to the rear. This configuration makes the motors 33% shorter in size than different chain drive motors, with solely a one-centimeter enhance in width. Lowering the motor’s house declare simplifies set up and frees OEMs to extend the scale of the chains driving the wheels, which may enhance the lifetime of the machine.
The elevated house created by the bigger rotary group allows a return to confirmed multidisc brake know-how, which affords sturdy parking torque in addition to easy emergency stopping. In contrast to canine clutch brakes, which produce harsh emergency stops and put on out extraordinarily shortly — generally 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 lowered friction and movement 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 power within the type of warmth.
Danfoss Thorx motors have reinvented cam lobe know-how, eliminating shortcomings whereas sustaining the know-how’s sturdy factors. All motor applied sciences have their place, and with its full motor portfolio, Danfoss has the correct know-how for the appliance, guaranteeing an ideal match.
