SMAC Moving Coil Actuators reached a cycle rate of 2400ppm (40Hz) with its new LCB model electric actuator, meeting the target set by several packaging OEMs. In contrast, the fastest pneumatic actuators generally reach a peak speed of 1200ppm. By doubling the cycle rate, SMAC says its electric actuators can greatly improve the efficiency of eject, divert or sorting applications - and without the need for any air consumption.
SMAC electric actuators can now reject or divert a single container at line speeds over 2400 containers/minute. Movement of container is smooth, fast and gentle thanks to the Soft-Land feature. The container does not tip over because of force and velocity control.
The LCB already made news earlier in 2017 by more than doubling the force in same package size as existing LCA actuators with only a minimal increase in price, enabling SMAC to continue its strategy of reducing prices by 35 per cent every five years compared with the previous SMAC series, a practice the actuator manufacturer has been following since 1995.
In addition, force more than doubles with the LCB over comparable LCA actuators due to a much higher Flux Density (>10k Gauss) in the Moving Coil Actuator magnetic circuit. For example, the 155 x 88 x 30mm sized LCB25 can produce up to 80N compared with 25N in the similarly sized LCA 25. Furthermore, accelerations with the new LCB now exceed 100 'g'; this makes SMAC a competitive option for some higher-force applications previously dominated by pneumatic actuators.
SMAC's built-in sensor feedback system gives its Moving Coil Actuators the mechatronic ability to 'do work and verify its success at the same time.' This would allow the actuators to quality check key processes 100 per cent in real time and feedback the results.
SMAC Moving Coil Actuators are descried as true 'mechatronic solutions', meaning that the actuators have capabilities such as programmable and controllable position, velocity and force, high accelerations, cycle life of well over 100 million, and a patent-pending Soft-Land' capability. The Soft-Land capability is particularly useful when performing handling, assembling or measuring fragile parts.
