Medical Equipment Motion Control
Medical imaging equipment OEMs and integrators building MRI, CT, DR, and SPECT systems — gantry rotation, hospital bed positioning, detector column motion, with stringent certification and lifecycle requirements.
Motion control for medical imaging — MRI / CT / DR / SPECT gantry, bed, and column actuation. Kinco is the No.1 domestic motion control supplier to China's medical imaging industry, with a 0.1% field failure rate (vs ~0.3% industry typical), 15+ years of partnership with Siemens and United Imaging, and component lifecycle commitments of 10-year supply + 10-year maintenance.
FIG.08 MEDICAL IMAGING JD + SMH UL 61800-5-1 Where this recipe fits
Medical imaging equipment — MRI scanners, CT systems, DR X-ray, and SPECT cameras — relies on precise, low-noise, high-reliability motion control for gantry rotation, hospital bed positioning, and detector column actuation. The industry's traditional dependence on imported European/Japanese motion suppliers introduces long lead times and high cost. Kinco addresses these pain points with a localized supply chain, motion control solutions tailored per equipment tier (low-end/mid-range/high-end), and lifecycle commitments aligned with medical device service lifespans.
What the system needs to do
CT Gantry Motion
- Belt drive (low cost, mechanical complexity, slippage risk) vs Direct drive (better accuracy, faster <0.25s, higher cost)
- Low-end CT: JD430 + SMH incremental encoder motor
- Mid-range CT: JD620 + SMH absolute encoder motor
- High-end CT: JD640 + SMH absolute encoder motor (or frameless direct drive)
Hospital Bed & Column
- MRI bed: OD124S compact drive + SMH motor (space-constrained installations)
- DR column: FD114-CS-000 drive + integrated Maxon/Dunker motor+reducer + TUI 2.0 HMI
- Brushed motor servo control for precise position retention
SPECT & Other
- SPECT gantry: JD620 + SMH motor (or JD620 + frameless direct drive)
- Auxiliary axes: iSMD series integrated servo for compactness
- EtherCAT trend across new high-end installations
Multi-brand component selection
The list below is a starting point. Final part numbers, quantities, and accessories are confirmed during RFQ based on motor power, I/O count, protocol, and certification scope.
| Role | Component | Specification |
|---|---|---|
| DRIVE-LOW | Kinco JD430 | Low-end CT gantry · 200–415V · multi-bus |
| DRIVE-MID | Kinco JD620 | Mid-range CT / SPECT gantry |
| DRIVE-HIGH | Kinco JD640 | High-end CT gantry |
| MOTOR | Kinco SMH (incr. encoder) | 200W–7.5kW · for low-end systems |
| MOTOR | Kinco SMH (abs. encoder) | 200W–7.5kW · for mid/high-end systems |
| MICRO | Kinco OD124S | Compact drive · MRI hospital bed |
| MICRO | Kinco FD114-CS-000 | Narrow column installations (DR) |
| HMI | Kinco TUI 2.0 | DR control HMI |
| INTEGRATED | Kinco iSMD series | Auxiliary axes · STO SIL3 |
Reference comparison: vs imported European/Japanese medical motion suppliers.
Alternative selection reference only. Final compatibility must be verified by power rating, I/O count, protocol, software logic, cabinet layout, safety requirements, and local approval.
How we size each component
- Tier-based BOM selection: Low-end (JD430+incremental) / Mid-range (JD620+absolute) / High-end (JD640+absolute).
- Direct drive (frameless) recommended for new high-end designs requiring sub-0.25s gantry positioning.
- Compact drives (OD124S, FD114) where mechanical envelope is the primary constraint (e.g., column-mounted, in-bed).
- Absolute encoder motors essential when post-power-loss position recovery is required for patient safety scenarios.
Practical notes for cabinet build
- Medical-grade EMC compliance per EN 61000-3 mandatory for installed environments
- Drive enclosure grounding to medical equipotential bonding bar
- Shielded encoder cables with strain relief; aerial-plug connectors for movable assemblies
- Battery-backup for absolute encoders sized for declared product lifecycle
Coming from a legacy brand
- Replacing imported European/Japanese motion stacks requires re-validation of dynamic motion profile, EMC immunity, and post-failure behavior per medical device QMS.
- Existing equipment-level FDA / CE-MDR clearances do NOT carry over — substantial change to motion subsystem may trigger re-certification scope. Confirm regulatory pathway before commitment.
- Component-level certification (UL 61800-5-1, EN 61000-3) provided by Kinco does not constitute system-level medical device certification — equipment OEM remains responsible.
When to use this recipe — and when not to
Good fit
- Medical imaging OEMs seeking to localize motion supply chain
- Equipment manufacturers replacing end-of-life imported drives within an existing platform
- New high-end CT/MRI/SPECT designs targeting direct-drive gantry
Not the right fit
- Class III implantable or life-support equipment requiring extreme safety qualification
- Equipment under active FDA 510(k) or CE-MDR clearance review where motion subsystem change would invalidate filing
- Cryogenic or hyperbaric medical environments outside standard component rating
