Abstract: An electronically commutated motor driving module for driving a motor includes a voltage detector, an electronically commutated motor driver, a current detector, a voltage converter, and a controller. The voltage detector detects supply voltage to generate a voltage detection signal. The electronically commutated motor driver is supplied by the supply voltage to generate, according to an electronically commutated signal, an operating current for driving the motor. The current detector detects the operating current to generate a current detection signal. The voltage converter converts the supply voltage into an internal voltage. The controller is supplied by the internal voltage and generates the electronically commutated signal according to a plurality of control parameters. When the controller determines that a specific event has happened according to the control parameters, the controller stops generating the electronically commutated signal and then stores the control parameters.

Abstract: A nebulizer includes a medicament storage module and a nebulizing unit. The medicament storage module includes an inclined bottom wall, a tubular sidewall, and a guiding part. The inclined bottom wall is inclined at an inclination angle. The tubular sidewall is connected with a periphery of the inclined bottom wall. A storage chamber is defined by the inclined bottom wall and the tubular sidewall collaboratively, and a liquid medicament is accommodated within the storage chamber. The tubular sidewall has an outlet, and the inclined bottom wall is extended downwardly to the outlet. The guiding part is arranged around a junction between the inclined bottom wall and the tubular sidewall. The nebulizing unit is disposed on the medicament storage module and aligned with the outlet. The liquid medicament outputted from the outlet is nebulized into a plurality of mist droplets by the nebulizing unit.

Abstract: A motor driving circuit including a first and a second driving signal output circuit is configured to selectively output a six-step square wave driving signal from the first driving signal output circuit, or a space-vector driving signal from the second driving signal output circuit to an inverter to drive a motor according to whether an operating power exceeds a power threshold. The first driving signal output circuit is configured to generate the six-step square wave driving signal. The second driving signal output circuit is configured to generate the space-vector driving signal.

Abstract: A motor system with a current sensorless control includes a motor, a drive module, and a motor control module. The motor control module controls the motor to rotate through the drive module. The motor control module includes a command generation module, a command conversion module, and an angle generation module. The command generation module generates speed information and transmits the speed information to the angle generation module, and the command generation module generates a voltage command and transmits the voltage command to the command conversion module. The angle generation module generates an electrical angle. The command conversion module converts the voltage command and the electrical angle into a control signal. The motor control module adjusts a phase of a motor input voltage to meet a phase of a motor input current according to the control signal.
