The invention discloses a shade roller with a high voltage direct current motor, which comprises that: one end of a clockwise option switch (3) and one end of an anticlockwise option switch (4) are respectively connected with a first output end of an AC power supply, and the other ends of the two switches are connected with a first power input end of the high voltage direct current motor (61) respectively through a half-wave rectifying circuit, and also connected with a first end of a first resistor (71) respectively through the half-wave rectifying circuit; a charge pump (7) and a charge control circuit (8) are connected in parallel between a second end of the first resistor (71) and a second output end of the AC power supply; the second end of the first resistor (71) is also connected with a control electrode of a triode AC semiconductor switch (73); and a T1 electrode and a T2 electrode of the triode AC semiconductor switch (73) are respectively connected with the second output endof the AC power supply and a second power input end of the high voltage direct current motor (61). The high voltage direct current motor consisting of low-cost electronic components is applied in theshade roller, the cost is reduced and the efficiency is improved.
Description
technical field [0001] The invention relates to a curtain reel, in particular to a high voltage direct current motor curtain reel. Background technique [0002] The curtain reel of the common electric curtain on the market is driven by a fixed phase split capacitor (PSC) induction motor. By energizing the PSC motor, the motor rotates clockwise or counterclockwise to drive the curtain up and down. like figure 1 As shown, it is the circuit connection diagram of the existing curtain reel motor, which is powered by 230V mains AC power supply 1, and one end of the power supply 1 is respectively connected to the clockwise (CW) selection switch 3 and the counterclockwise (CCW) selection switch 4, two The selector switches are respectively connected to the driver 5, and the other end of the power supply is connected to the driver through the common line (COM) 2, and the driver 5 is connected to and drives the PSC motor 6. Both the CW selector switch 3 and the CCW selector switch 4...
