Embodiment Construction

[0059] Since the present invention discloses a single-phase motor drive device configured with an energy-saving control module, especially an energy-saving control module is configured in a single-phase motor drive device, and at the same time, it can be recommutated by the phase change configured in the single-phase motor drive device. A point sampling circuit is used to generate a periodic specific time width, and within the range of this specific time width, at least one control signal is selected for modulation, so that the driving current on the induction coil forms a symmetrical and smooth drive in a specific time width current to make single-phase motor speed more stable and more energy efficient. However, because the present invention is used to drive the single-phase motor driver to generate the control signal of the drive current and Figure 8B and Figure 9B The ones shown are the same, so in the following description, a complete description will not be made; in ad...

Abstract

The invention relates to a single-phase motor-driving device with an energy saving module, which is characterized by comprising an output-stage control circuit, a control interface and an energy saving module, wherein the output-stage control circuit is used for providing a plurality of driving signals to drive a first driving transistor to be complementally conducted and not conducted with a second driving transistor, and a single-phase motor is driven by an induction coil to rotate; the control interface is used for providing at least one control signal; the input end of the energy saving module is connected with the control signal, and the output end of the energy saving module is connected with the output-stage control circuit. By the provided control signals of the control interface, the output end of the energy saving module can lead the output-stage control circuit to close or restart the driving signals, and the single-phase motor is stopped or rotated again.

Description

technical field [0001] The present invention relates to a drive device for a single-phase motor, in particular to a drive device capable of saving energy and improving the operating efficiency of a single-phase motor. The single-phase motor is stopped or re-rotated through an energy-saving control module, and at the same time is controlled by a single-phase motor. When the phase motor rotates to the magnetic pole commutation region, it continues to provide multiple driving voltage pulses, so as to prevent the driving current from generating a whole period of zero current state in the commutation region. Background technique [0002] First, please refer to Figure 8A and Figure 8B , a schematic diagram of a single-phase motor drive device and its drive signal in the prior art, where Figure 8A A schematic diagram of a single-phase motor drive circuit in the prior art, and Figure 8B Corresponding to Figure 8A Schematic diagram of the driving waveform (or driving signal) of...
