A motor control method is provided. The method includes: receiving a plurality of voltage control signals from a rotation speed controller to output a plurality of PWM signals; receiving the plurality of PWM signals to output three phase currents, so that a motor rotates; sensing three phase current values of the three phase currents; directly calculating a real rotor angle of the motor according to two of the three phase current values; and adjusting the plurality of the outputted voltage control signals according to an expected rotor speed and the calculated real rotor angle, so as to make the real rotor speed of the motor reach the expected rotor speed.

Motor controller and motor control method

A technique for adjusting a display angle of an electronic apparatus includes capturing, by an image capturing module (of the electronic apparatus), images of a user with respect to a display device (of the electronic apparatus) at a reference first position and a second position. A processing module (of the electronic apparatus) provides an indication when the user exceeds a predetermined threshold in moving from the first position to the second position. A controlling module (of the electronic apparatus) causes a first driving module (of the electronic apparatus) to drive rotation of a first rotating module (of the electronic apparatus) in response to the processing module indicating the displacement has exceeded the predetermined threshold. The first rotating module is coupled to a base unit portion of the electronic apparatus.

Techniques for adjusting a position of a display device based on a position of a user

A power supply system for an information handling system is provided. The information processing system is electrically coupled to an AC power source and includes at least one computer unit. The power supply system includes: at least one AC power supply unit electrically coupled to the at least one computer unit and the AC power source; at least one DC power supply unit electrically coupled to the at least one computer unit; and a backup power unit electrically coupled to the at least one DC power supply unit. In response to the at least one AC power supply unit not supplying power, the at least one DC power supply unit supplies power to the at least one computer unit. A data center having the power supply system is further provided.
