VCAR0022-0448-00A Voice Coil Motor 22N Peak Force 44.8mm Stroke Wide Speed Range

Product Overview

The VCAR0022-0448-00A is a wide-speed-range cylindrical voice-coil motor in SUPT MOTION’s VCAR series. At 25 °C, it offers a total stroke of up to 44.8 mm, a peak thrust of up to 22 N, and a continuous thrust of 11.4 N. This model of voice coil motor is specifically designed for linear motion systems, enabling smooth operation from ultra-slow creeping speeds to high-speed reciprocating motion, while providing precise speed control across the entire stroke range.

Voice coil motors are inherently capable of operating over a wide speed range because thrust is proportional to coil current and independent of speed. Unlike ball screws and belt drives, it is free from variations in friction, backlash, and mechanical resonance that limit the speed range. Consequently, the VCAR0022-0448-00A delivers uniform force output at rest, at low speeds, and at high speeds—a decisive advantage for speed-sensitive processes such as dispensing, coating, and scanning.

With a stator diameter of 48 mm and a length of 75.7 mm, this actuator features a robust construction while keeping the moving mass to just 52 grams. The direct-drive principle ensures high dynamic stiffness, fast response, and micron-level repeatability under closed-loop control. Each voice coil motor is manufactured in accordance with ISO 9001 standards and is CE-certified; all units undergo quality testing for thrust, resistance, and insulation performance prior to shipment.

In addition to its long stroke, the VCAR0022-0448-00A features excellent force linearity, as the coil operates within a carefully optimized magnetic field throughout the entire stroke. Consequently, predictable force output is achieved at every position, which greatly simplifies servo tuning and improves contour accuracy in multi-axis machine tools. This actuator can be equipped with free-hanging leads, connectors, or custom-length cables, and can incorporate optional linear guides to support external loads while the motor provides driving force.

FAQ

Q1: What speed range can this motor achieve?

The motor can operate from near-zero creep speed up to several hundred millimeters per second, depending on the driver voltage and load. Because voice coil force is current-controlled and speed-independent, velocity remains stable across the full 44.8 mm stroke. For your specific load and motion profile, we can provide a dynamic calculation including acceleration, settling time and required driver current.

Q2: How is positioning accuracy achieved with such a long stroke?

We recommend a linear encoder with the desired resolution plus a servo driver with position and velocity loops. The direct-drive, zero-backlash construction ensures that the commanded position is maintained without mechanical drift.

Q3: Can the stroke be customized?

Yes, the VCAR series offers strokes from 1 mm to over 60 mm across different frame sizes. Custom strokes, force levels and mechanical interfaces can be developed for volume applications.

Q4: What is the duty cycle and thermal behavior?

The continuous force rating of 11.4 N at 25 ℃ defines the safe continuous duty. For higher force or longer duty, we can add thermal management options or recommend a larger model from the VCAR family.

Q5: How long does delivery take?

Sample orders ship within 3 to 5 working days, and production orders within 7 to 15 working days. The MOQ is 1 piece for evaluation.
