Precision Voice Coil Motors for Specialist Motion Applications
Voice coil motors (VCMs) provide smooth, precise, and highly dynamic linear motion using a direct electromagnetic force. With no commutation, no cogging, and no mechanical contact between moving parts, they offer exceptional acceleration, repeatability, and friction‑free operation. These characteristics make VCMs suitable for a narrow range of high‑performance applications across UK medical, scientific, and advanced automation sectors.
Where Voice Coil Motors Are Used
VCMs are typically selected for applications that require:
- High‑bandwidth force control for test, measurement, and micro‑assembly
- Smooth, cog‑free motion for optical, imaging, and scanning systems
- Fast, precise positioning in semiconductor and laboratory equipment
- Bidirectional actuation with predictable force‑to‑current behaviour
Because these motors are highly specialised, they are generally used in engineered systems rather than general‑purpose automation.
Voice Coil Motor Options
- Linear Voice Coil Motors — Direct linear force for precision actuation and high‑speed positioning.
- Rotary Voice Coil Actuators — High‑speed angular motion for optical and scanning mechanisms.
- Integrated Voice Coil Actuators — Housed assemblies with guidance for simplified mechanical integration.
Engineering‑Led Selection
Due to the specialised nature of voice coil technology, motor selection is typically carried out on a case‑by‑case basis. Our UK engineering team works closely with Celera Motion to review application requirements, performance targets, and integration constraints to ensure the correct actuator is specified.
