Abstract: A bi-power motor controlling system includes a motor, a system apparatus and a motor controlling apparatus. The system apparatus has a rotational-speed target value for determining the targeted rotational speed of the motor. In addition, the system apparatus outputs a first power and a second power to the motor and the motor controlling apparatus, respectively. The motor controlling apparatus detects the motor to obtain a first rotational-speed value of the motor, and then adjusts the rotational speed of the motor to a second rotational-speed value according to the first rotational-speed value. Then, the motor controlling apparatus further generates a rotational-speed feedback signal to the system apparatus. The system apparatus adjusts the outputted first power in accordance with the rotational-speed feedback signal to make the rotational speed of the motor reach the rotational-speed target value.

Abstract: A motor control apparatus and a motor control method determine whether the motor is in a back-pressure area so as to provide different rotation-speed control signals. When the fan is in the low duty cycle, a first circuit loop is switched on, so that the fan has more accurate rotation speed. When the fan is in the high duty cycle, a second circuit loop is switched on, so that the rotation speed of fan does not be limited to a constant rotation-speed as the fan enters the back-pressure area. Thus, the fan has larger airflow quantity and higher airflow pressure.

Abstract: The water provisioning system mainly contains a selection switch, a water volume switch, a human-machine interface (HMI), a RO waste water recycling device, an electromagnetic valve, a RO water purification device, an antichlor device, a aeration pipe assembly, a first ozone module, and a second ozone module. The selection switch selects a type of water to use. The RO water purification device filters water from a low-temperature water source, stores purified water in a storage barrel, and provides high-quality drinking water. The 70% water from the RO water purification process that fails the drinking water standard is recycled through the RO waste water recycling device. The low-temperature water source is connected to a antichlor device and the water is therefore dechlorinated. The first and second ozone modules are used to produce ozonated water and to release ozone through the aeration pipe assembly into the kitchen cabinet for deodorization and sterilization.
