Overview
Versa Drives offers a compact automatic door operator drive built around a matched 90 W Permanent Magnet Synchronous Motor (PMSM) and controller. This integrated motor–drive set is designed for:
- Elevator car doors and landing doors in vertical transport systems
- Automatic sliding doors in hospitals, commercial buildings and cleanrooms
- Other automatic doors within the torque and speed range of the 90 W PMSM kit
The controller runs from a single-phase 200–264 V AC, 50 Hz supply and uses encoder-based vector control to deliver smooth, quiet motion, precise positioning and repeatable open/close profiles. OEMs can use this as a ready platform for new door systems or to replace older motor–drive solutions with a more efficient PMSM-based alternative.
Key Features
- Integrated solution: 90 W PMSM motor with matching controller, designed as a single door-operator platform.
- Single-phase input: 200–264 V AC, 50 Hz input for easy installation in standard building electrical systems.
- Encoder-based vector control: closed-loop vector control with incremental encoder feedback for accurate speed and position control at low speeds.
- Door-specific protections and safety: extensive electrical and motion protections, including braking support on power fail.
- Encoder interface: compatible with three-channel incremental encoders and PWM output for rotor position within one revolution.
- Flexible I/O: opto-isolated logic inputs and outputs for open/close commands, interlocks and status indications.
- Compact footprint: suitable for mounting inside door headers and compact control panels.
- Designed for OEM integration: intended for elevator OEMs, door-system integrators and vertical-transport solution providers.

Applications
- Elevator car doors and hoistway/landing doors in residential, commercial and institutional buildings
- Automatic sliding doors in hospitals, ICU/OT entries, cleanrooms and labs
- Glass and aluminium sliding doors at retail storefronts and office entrances
- Light industrial and warehouse sliding doors within the power/torque range of the 90 W PMSM kit
- Other specialised door or barrier systems requiring controlled speed profiles and accurate stopping
Integration with Door Controllers
- Opto-isolated inputs accept commands such as Open, Close, Stop, Direction and speed mode.
- Logic outputs provide status feedback for door position and fault conditions to the main controller.
- Encoder feedback supports accurate speed profiling and soft landing at open/closed positions.
- Braking relay output allows the PMSM to be electrically braked in power-fail conditions (with appropriate mechanical design).
- Built-in protections and diagnostics simplify certification and compliance (when integrated into a complete system).
