The unit does not use an inverter and connects directly to an ac line. The high torque at low speeds eliminates gearing and the need for a separate controller cabinet, which results in reduced chance of damage to wiring post installation; no gearbox losses, less noise — no gearing or PWM whine, and no RFI or other PWM switching problems.
