Water Pump Solution:

Introduction:

The high/low voltage water pumps (or drain pump) uses the MDF101A as the core MCU, which is based on a single/double resistive sensor-less FOC algorithm to achieve high efficiency and low vibration operation to ensure that the water in drainage system can be drained efficiently.

Features:

- Based on single/double resistor non-inductive FOC algorithm, realizing high efficiency and low vibration operation, closed-loop start ensures fast and smooth zero-speed start.
- Support soft start and fast start (maximum speed within 1 second).

- Constant speed/constant power control.

- 5-segment/7-segment SVPWM can be switched freely.
- Integrated blocking detection, phase loss protection, over/under-voltage protection and over-current protection, real-time feedback of the operating status to improve system reliability.
