Electronic assembly and electronic apparatus

A motor deceleration method for a motor driving system is provided. The motor driving system outputs a driving signal containing a voltage value, a current value and a frequency value for driving a motor. When a deceleration of the motor is launched, the descent speeds of the voltage value and the frequency value are controlled according to a preset deceleration time period. Then, a voltage compensation value is generated according to a result of comparing the current value with a preset current level, and the voltage value is increased according to the voltage compensation value, so that the current value is increased to the preset current level. According to a frequency compensation value, the current value is increased to and maintained at the preset current level. Finally, the rotating speed of the motor is gradually decreased to a preset speed.

An electronic module includes a first circuit board having a first surface, a second circuit board having a second surface, first electronic components on the first surface, second electronic components on the second surface, a first conductive fence, and a second conductive fence. The first conductive fence encloses the first electronic components and has a first opening exposing the first electronic components. The second conductive fence encloses the second electronic components and has a second opening exposing the second electronic components. The first opening of the first conductive fence joints the second opening of the second conductive fence, such that the first electronic components and the second electronic components are surrounded by the first circuit board, the second circuit board, the first conductive fence, and the second conductive fence. At least one of the first electronic components is higher than the first conductive fence.

Electronic module

A moving module and an electronic device are provided. The electronic device includes a first body, a second body, and the moving module disposed between the first and second bodies. The moving module includes a rail, a moving element, and an elastic element. The moving element is in contact with the rail. The elastic element is connected between the moving element and the first body. When the moving element moves from a first end of the rail to a curved portion of the rail, a force exerted on the elastic element by the moving element is gradually increased. When the moving element passes the curved portion, an elastic restoration force of the elastic element drives the moving element to move toward a second end of the rail. When the moving element reaches the first end or the second end, the first body and the second body interfere with each other.

Half-controlled silicon-controlled rectifying system and method thereof

A method of balancing the rotation of a motor is provided. Whether or not the motor is in a balanced rotation is determined by detecting whether the variation of a power-factor angle is less than or equal to a preset balance angle according to the principle that the load on a motor has an effect on the variation of the power-factor angle. The determined balance state of the motor is used to adjust the rotation speed of the motor.
