Product Overview

The VCAR0011-0050-00A is a high-acceleration cylindrical voice coil motor in the SUPT MOTION VCAR series, designed specifically for applications requiring rapid startup, quick stabilization, and continuous high-frequency response. At 25 °C, this model delivers a peak thrust of 11.4 N and a continuous thrust of 2.1 N. Its lightweight moving-coil assembly, weighing just 11.2 g, provides an extremely high thrust-to-mass ratio, enabling the motor to reach its target speed in a matter of milliseconds.

Unlike traditional rotary motors converted to linear motion, cylindrical voice coil motors generate thrust directly through the interaction between the coil current and the permanent magnetic field. These motors require no gearboxes, couplings, or lead screws, which means zero backlash, zero cogging effects, and virtually no hysteresis. Consequently, when used in conjunction with a suitable encoder, they deliver exceptionally smooth motion, high-frequency response, and micrometer-level repeatable positioning accuracy.

The VCAR0011-0050-00A offers a total stroke of 5 mm, making it ideal for short-stroke, high-speed pick-and-place, focusing, scanning, and oscillation tasks. With a compact stator diameter of 24 mm and a length of 17.2 mm, it can be easily integrated into space-constrained machine modules. This motor features a brushless design, is maintenance-free, operates with extremely low noise and minimal heat generation, and is manufactured to ISO 9001 standards and CE-certified, ensuring reliable operation in industrial environments.

The voice-coil motor consists of a precision-wound copper coil that moves within a high-energy rare-earth magnetic circuit, eliminating the need for brushes, commutation electronics, or mechanical transmission mechanisms. This simple yet robust construction not only reduces points of failure but also ensures that the output force is proportional to the applied current, providing designers with a predictable and easily controllable actuator. When combined with a suitable linear amplifier and position feedback, the VCAR0011-0050-00A can be configured for force control, speed control, or precise point-to-point positioning modes, depending on application requirements.

FAQ

Q1: How fast can this motor accelerate?

With an 11.2 g mover and 11.4 N peak force, the theoretical peak acceleration is extremely high. The actual acceleration depends on the load mass, driver current limit and stroke, and our engineers can help you calculate the dynamic performance for your specific load.

Q2: Can the motor operate continuously at high frequency?

Yes, within the continuous force rating of 2.1 N, the motor can operate at high frequency without overheating. For duty cycles that exceed the continuous rating, forced air cooling, duty-cycle derating or a larger frame size from the VCAR series is recommended. Our application engineers can simulate your motion profile and suggest the optimal model.

Q3: What position feedback options are available?

We recommend linear encoders, Hall sensors or LVDT position sensors depending on the required resolution. SUPT MOTION can provide integration guidance for closed-loop servo control.

Q4: Is the motor suitable for cleanroom environments?

Yes. The brushless, slotless construction generates no wear debris, and the motor can be supplied with cleanroom-compatible materials and cabling for semiconductor and medical applications.

Q5: What are the payment terms and shipping options?

We accept T/T, PayPal and Western Union. Samples ship within 3 to 5 working days by international express, and production orders are delivered within 7 to 15 working days.
