<p>A drive circuit of an electric curtain body and an electric curtain body. The drive circuit of the electric curtain body comprises a motor, a switching module used for controlling an operating state of the motor, and a power supplying module coupled with the switching module and providing electric energy for rotation of the motor. The switching module directly couples a positive pole or a negative pole of the power supplying module to any input end of the motor. Because the switching module and the power supplying module are used, the power supplying module directly provides a working power supply for the motor, and the switching module can switch the positive pole or the negative pole of the power supplying module to any input end of the motor, that is, can control reversal of polarities at two ends of the motor; in this way, control of forward and backward rotation of the motor is achieved, and an objective of controlling opening and closing of the curtain body is achieved. When the curtain body is moved to a preset location, the switching module is controlled to couple electrodes at two ends of the motor to the positive pole of the power supplying module; in this way, stalling of the motor is achieved and the curtain body is maintained stationary at the preset location.</p> |
