Harold Beck & Sons, Inc. exhibited with MagnaDrive at the WEFTEC 2011 tradeshow. MagnaDrive Adjustable Speed Drive (ASD) couplings transmit torque from a motor to a load across an air gap. There is no physical connection between the two sides and the transmission of torque is done so using rare-earth magnets. Beck electric actuators are connected to a lever arm on the ASD which modulates the air gap spacing through a 4-20 mA demand signal, in turn, controlling the speed of the transferred load.
Please watch the short demonstration video.
