Control method for single encoder of double torque motors

The invention discloses a control method for a single encoder of a double-torque motor. The method is applied to a bridge plate of a large gantry, and comprises the following steps of: 1) respectively mounting a main torque motor and a slave torque motor which are the same on two sides of the bridge plate; 2) installing an encoder on the main torque motor; 3) connecting the master torque motor and the slave torque motor with a driver; and (4) the encoder is connected with the driver. According to the control method of the double-torque motor and the single encoder, the mode that two identical torque motors are driven through one encoder is adopted, encoders and drives are saved, and the control method has the advantages that control is easy and convenient, torque is increased, and cost is reduced. 本发明公开了一种双力矩电机单编码器的控制方法。该方法用于大型龙门的桥板上，其包括以下步骤：1)将相同的主力矩电机和从力矩电机分别安装在所述桥板的两侧；2)在所述主力矩电机上安装编码器；3)将所述主力矩电机和所述从力矩电机均与一台驱动器相连接；4)将所述编码器与所述驱动器相连接。本发明中的一种双力矩电机单编码器的控制方法采用由两台完全相同的力矩电机通过一个编码器驱动的方式，节省了编码器和驱动，并且具有控制简便、提升扭矩、降低成本
