Abstract

The invention relates to the technical field of motor driving devices, in particular to a design and method for preventing misoperation of a motor driving device, the motor driving device comprises a servo motor, a driving wheel, an encoder, a reflecting plate and a light sensor, and the servo motor is used for controlling forward driving or reverse driving of the driving wheel. Hardware and software for monitoring misoperation are provided, a reflecting plate is installed on a driving wheel, three optical sensors are operated from the outside, the device has the advantage of being capable of immediately stopping when a motor is driven to drive an engine in an unexpected direction, the direction can be judged according to an input sequence, and a control signal for controlling the motor is captured and compared and analyzed; the light sensor can sense actual rotation of the driving wheel, so that the direction is definitely defined, if forward rotation occurs in a program command, whether forward rotation actually occurs or not is analyzed according to the driving wheel sensing light sensor, and if it is found that the driving direction is opposite under the normal condition, an error signal is transmitted to the driving controller, so that driving is stopped.

Description

technical field [0001] The invention relates to the technical field of motor drive devices, in particular to a design and method for preventing malfunction of a motor drive device. Background technique [0002] Servo motor, also known as servo motor, refers to the engine that controls the operation of mechanical components in the servo system, and is an auxiliary motor indirect transmission device. The servo motor can control the speed and the position accuracy is very accurate. It can convert the voltage signal into torque and speed to drive the control object. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an actuator , and has the characteristics of small electromechanical time constant and high linearity. It can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft. It is divided into two categories: DC and AC servo motors...
