Linear actuators are ideal mechatronic solutions for a myriad of miniature X-Y, syringe pump, slide, valve, leveling and lift applications. Hybrid linear actuators deliver high performance, exceptional endurance and long life in a very compact, economical package.
As there are no commercially available mechanical equivalents to “captive, non-captive and external linear” actuators in the servo motor market, the ability to drive standard hybrid actuators in servo mode provides equipment designers a reasonal and cost affective means to dramatically improve system performance. Nymotion LLC is pleased to introduce a full line of servo linear actuator drive/controls.

Note 1: An example of torque mode: Move assembly A into assembly B. Ramp up and maintain a constant 15 lbs thrust into B for 90 seconds while the epoxy cures.
Note 2: Efficiency and power management. In most applications, servo drives are significantly more energy efficient than comparable constant current stepper drives. As hybrid servo motors are in fact true servo motors, drawing as much current as required to accelerate or hold a load, the designs are inherently more efficient. On the other hand, Hybrid step motors are sized and their drives are set to provide a torque (= current) with a safety margin of 1.35 X or higher.
Nymotion NYT-AP Series drive/controllers provide machine designers the means to use hybrid linear actuators in servo mode. The outcome is higher throughput, lower audible noise, lower risk (closed loop) performance with a significantly lower carbon footprint.
