The Technology
Why FOC
changes everything.
Field-Oriented Control continuously calculates and applies the exact magnetic field needed to produce smooth, precise torque. The result: near-silent operation, maximum efficiency, and response times measured in microseconds.
01
Silent operation
Zero cogging torque. Motors run whisper-quiet.
02
Peak efficiency
97.8% — less heat, longer battery life.
03
Instant response
Sub-millisecond torque control loop.

FOC advantage
Smooth sinusoidal current eliminates the torque ripple, vibration, and inefficiency of conventional trapezoidal control.
