Sabvoton SM7245
Budget Sabvoton SM-series 24-72V / 45A DC motor controller for e-bikes and e-scooters — a higher-voltage (72V-class) SM model. Lookup-table sine-wave drive (NOT true FOC, unlike SVMC/ML/MZ) with square-wave and sensorless (no-hall) modes. Pairs with UART No.2 displays (SW900/S866/M8).
In brief: 24–72V controller. 45A continuous. Sinewave, dual mode, self-learning support. From $35.
