105N Thrust High Response Cylindrical Voice Coil Motors For Automated Equipment

Product Overview

The VCAR0105-0164-00A is a cylindrical voice-coil motor specifically designed for high-speed motion control. It utilizes the moving-coil principle to directly convert electrical current into linear thrust, with no gears, belts, or lead screws in the motion chain. This direct-drive design eliminates backlash and mechanical compliance, enabling the motor to accelerate rapidly and stabilize at the target position within approximately one millisecond.
This voice coil actuator is rated at 20.1 V DC, delivers a peak thrust of 105 N, and has a total stroke of 16.4 mm, making it suitable for short-stroke, high-speed positioning tasks. A high-energy neodymium magnet assembly and a low-mass coil are integrated within the cylindrical housing, thereby maintaining low moving mass and high acceleration.
Each unit is wound and balanced under strict process control to ensure consistent force output across all units. Flexible mounting options and free-hanging leads simplify OEM integration. The voice coil motor accepts simple current commands and generates smooth, controllable force across the entire stroke range, making servo tuning simple and intuitive.

Solution

Many automated devices experience extended cycle times due to slow and indirect drive systems. Rotating motors coupled via gearboxes generate backlash, friction, and reflected inertia, which slow response times and make precise positioning difficult.
This voice-coil motor addresses this issue by applying force directly to the load. Since the moving coil never comes into contact with the stator, there is no cogging effect, hysteresis, or mechanical backlash; consequently, step commands can be executed and stabilized within approximately one millisecond without oscillation.
The force is proportional to the current, making acceleration and deceleration curves easy to design and repeatable. The low moving mass also reduces energy consumption during cyclic operation. For throughput-oriented applications, this is a practical method for shortening movement and stabilization times and improving equipment productivity. Since there is no need for belt tensioning, coupling alignment, or gearbox lubrication, this direct-drive approach also simplifies maintenance.

Specifications

Application

This voice coil actuator is widely used in pick-and-place mechanisms, semiconductor processing, dispensing systems, high-speed sorting, valve actuation, optical focusing, and vibration testing, among other fields. In robotics, it drives the movements of lightweight gripper fingers and wrists, which must respond rapidly to sensor feedback.
Cylindrical voice coil motors are also well-suited for active damping and other short-stroke motion applications requiring rapid acceleration and smooth steady-state operation. This voice coil actuator is also used in active vibration cancellation and high-speed tool servo systems, which require force response times in the sub-millisecond range.

FAQ

Q: What is the service life of this motor?
A: The motor has no brushes and no sliding electrical contacts. The only moving part is the coil assembly supported by linear bearings, so service life is typically measured in tens of millions of cycles.

Q: Can force, stroke and voltage be customized?
A: Yes. SUPT MOTION offers custom windings, strokes from 1 mm to 60 mm and peak forces from 0.5 N to 3000 N. Provide your motion profile and we will match a suitable design.

Q: Which driver should I use?
A: A current-mode servo drive with position feedback is recommended. We can supply a matched driver and controller for a complete plug-and-play solution.

Q: Does the motor require an encoder?
A: An encoder is recommended for closed loop position control. For force or velocity control, a current-mode driver alone is sufficient.
