Not off-the-shelf steppers. Not repurposed hobby motors. True brushless DC servos with closed-loop FOC control, absolute position feedback, and integrated thermal protection.
Brushless DC with sinusoidal field-oriented control. Smooth, silent, and zero missed steps — ever. No stepper whine, no resonance dead zones.
The controller knows exact shaft position at power-on. No homing routine required. Instant recovery from power loss. True closed-loop at 1ms update rate.
Integrated Hall sensors for commutation plus NTC thermistor for real-time winding temperature monitoring. RigidPulse derates automatically before thermal limits.
RigidDrive motors are not available from any other CNC manufacturer. Purpose-wound for our 48V bus architecture with custom encoder integration.
Why it matters: Every competitor in our price range ships open-loop steppers or closed-loop steppers pretending to be servos. RigidDrive is true BLDC with field-oriented control — the same motor technology used in industrial robotics and EV drivetrains. The difference is felt in every cut: smoother surface finish, higher feed rates, zero stalling, and AI-responsive motion that steppers physically cannot achieve.
RigidDrive motors feature a custom rear shaft for direct-mount absolute encoder integration, 48V bus architecture, and branded housing. Available individually for builders, integrators, and the CNC community.
One motor, encoder-ready rear shaft, spec sheet, wiring guide. For builders replacing a single axis or prototyping.
Four matched motors for a complete machine build. 5% volume discount. Matched encoder kits available.
Custom winding specs, private labeling available. Integrators and machine builders building on the RigidDrive platform.
Encoder kits (AMT212B-V-OD + 3D-printed back cap) sold separately at Contact for Pricing or bundled with motor purchase.
