The company has developed an electromagnetic direct drive system that eliminates gear reducers, belt drives, fluid couplings, motor bushing, and virtually all interior wear parts. The lack of wear parts means nothing to adjust, break or replace. The company also states that the enhanced performance of the system can allow for doubling of throughput in some cases.
“This is truly a breakthrough long sought by the industry,” said Len Beusse, Vecoplan’s COO. The HiTorc Drive System is available exclusively on Vecoplan shredders.
“While durability and extremely low maintenance are highly valuable benefits of the HiTorc Dirve System, they pale in comparison to the performance features it delivers,” Beusse adds. The most efficient drive system made, HiTorc provides maximum torque and power under all conditions, regardless of rotor speed. Immediately upon startup, the rotation axis receives 300 percent torque, at 50 percent of rotor rpm it levels off at 100 percent torque, and continues at this torsion through 150 percent of rotor speed. Even at 200 percent rotor speed the HiTorc Drive System delivers 50 percent torque.
HiTorc also provides full speed control and the widest speed range available. Conventional shredder and granulator drive motors have a useable speed range of 0 to 100 percent with little control of actual rotor rpms. Veoplan’s Hitorc Drive System delivers a useable rotor speed range of between 0-200 percent with total control of rotor speed within these parameters.
The control can be achieve manually by the operator or automatically through computerized controls linked to sensors within the machine. With the HITorc Drive System it is feasible to network entire processing lines together, both pre- and post-size reduction, achieving perfect synchronization of in-feed and out-feed workflow.
The drive system also provides the quickest starting, stopping and reversing rotor action. About two seconds is all that is required to achieve any of these operations, all with absolutely no wear to the system.
According to Thomas Sturm, Vecoplan’s director of engineering, “Increased efficiency was the original force driving Vecoplan’s R&D engineers in the development of this system, and the results surpassed not only our goals, but anything we though possible. The HiTorc more than doubles the efficiency rating of traditional motors.”
The development of the new drive system was done via a joint effort between Vecoplan and K.E. Brinkman GmbH, a firm specialized in advanced motor solutions.
According to Vecoplan, while turning on a conventional drive motor will give an operator a current draw spike of between 700-1,200 percent FLA with only around 225 percent torque, the HiTorc and the current draw is reduced to 300 percent FLA with an immediate 300 percent torque output, a 100 percent efficiency rate.
With conventional motors the current draw continues to remain more than 100 percent until the rotor achieves 100 percent speed. The HiTorc’s current draw levels off to 100 percent at slightly over 40 percent of rotor speed.
“The level of speed control offered by the HiTorc Drive System also enables one to limit the maximum current draw and torque, according to the rating of your particular electrical service,” Sturm adds. “This represents a huge benefit with regard to power consumption, enabling shredders to consume as little as half the power to accomplish the same performance.”
Another ancillary benefit of the HiTorc Drive System is its noiseless operation. By eliminating wear parts it also eliminates the noise.
