[0002] The existing window-pushing motor precisely controls the two chain drive motors of the window-pushing motor to realize the complete synchronization of the double-chain push-out and retraction, avoiding the situation where the two chains are one high and the other low and damage the window; currently, motors are widely used in the industry The way of current detection is to judge whether one of the two chain motors has stalled. After one motor stops, the other motor will also stop immediately, realizing the function of starting and stopping the two motors at the same time. This synchronization method, Although the dual chains can start and stop at the same time, the synchronization effect is poor, and the speeds of the two motors cannot be kept completely consistent. Often, the double chains are fast and slow, and the two sides are high and the other low. Not only the window pushing effect is poor, but even Damage the windows; therefore, it is very necessary to invent a dual-motor synchronous device and control method at this stage

The invention discloses a dual-motor synchronization device and a control method. The dual-motor synchronization device comprises motors, a chain, a worm, a turbine, a chain wheel, a current detector and a voltage detector. The control method comprises the following steps: step 1, starting the motor; step 2, closed-loop detection; step 3, speed control; and step 4, current and voltage detection. The double-motor speed closed-loop control technology is adopted, speed detection is carried out on driving motors of the two chains, accurate speed control is achieved, the two motors are made to be free of load or loaded, or one motor is free of load and the other motor is loaded, and the two chains can be completely synchronous and consistent in speed when a window is pushed; on the basis of speed closed-loop control, current detection and voltage detection are added, closed-loop control of three dimensions of speed, voltage and current is achieved, all-directional real-time monitoring is conducted in the operation process of a double-chain motor, and it is guaranteed that in the window sliding process, two chains operate stably, powerfully and coordinately all the time.
