Capabilities
Controllers

Mission-critical control

One controller family spans Sapphire's machines and the OEM platforms built on them, engineered together in house.

About our controllers

Sensorless space vector modulation, no resolver or sense cables

Automotive-grade dual-core processors, up to 200 MHz and 125°C

Adaptive bearing control with gain scheduling and fault monitoring

Transfer function measurement, scope, and high-speed data logs

One integrated controller family

Machine control, bearing control, and the user interface come from one engineering team, tuned together rather than integrated from separate vendors.

Mission-critical hardware

Automotive-grade dual-core processors in delayed lock step, with overspeed, overcurrent, and thermal protection built in.

Insight, not just alarms

Bearing loading and vibration data describe process changes upstream, with a local GUI and remote monitoring that most machine controllers do not offer.

More about controllers

What protections are built in?

Overspeed, overcurrent, and thermal protections are managed in the controller with continuous monitoring.

Can operators monitor the system remotely?

Yes. Built-in sensors track pressure, flow, speed, and system dynamics for real-time process insight, and remote monitoring and predictive maintenance packages are available.

Does the machine need a position sensor?

No. Rotor position is derived electrically, with no resolver and no sense cables. The magnetic bearings use their own position sensors for levitation control.

Can the controller talk to our plant control system?

Yes. Interfaces to customer PLCs and HMIs are tested with customer hardware and software before shipment.
