Stepping motor-driven robot, Shenzhen ruite electromechanical Technology Co. , Ltd. is located in Shenzhen, Guangdong province, it is a stepping motor manufacturer integrating research and development, production and sales of stepping motor drivers, servo drivers, stepping motors, servo motors and spindle servo motors.
The company's core products include servo drivers, Hybrid Stepping Motor Drivers, servo motors and stepping motor manufacturers of various stepping motors. Motor commonly known as'Motor'
It refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. The motor uses the letter M (Old Standard D)
It is said that its main function is to generate driving torque. As a power source for electrical appliances or various machines, the generator is expressed by the letter G in the circuit. Its main function is to convert mechanical energy into electrical energy. 1.
According to the type of working power supply: it can be divided into DC motor and AC motor; 2.
According to the structure and working principle, it can be divided into DC motor, asynchronous motor and synchronous motor; 3.
According to the starting and running mode, it can be divided into: Capacitor-starting single-phase asynchronous motor, capacitor-running single-phase asynchronous motor, capacitor-starting single-phase asynchronous motor and split-phase single-phase asynchronous motor; 4.
According to the purpose can be divided into: driving motor and control motor; 5.
According to the structure of the rotor can be divided into: cage induction motor (The old standard is called squirrel cage asynchronous motor)And a wound rotor induction motor (The old standard is called wound asynchronous motor); 6.
According to the running speed, it can be divided into high-speed motor, low-speed motor, constant-speed motor and speed-regulating motor.
Low-speed motors are divided into gear reduction motors, electromagnetic reduction motors, torque motors and claw-pole synchronous motors.
There are mainly the following five motors on the robot.
Servo Motor Servo motor, also known as Executive Motor, is used as executive element in automatic control system to convert the received electrical signal into angular displacement or angular velocity output on the motor shaft.
It is divided into DC and AC servo motors. Its main feature is that when the signal voltage is zero, there is no rotation phenomenon, and the rotating speed decreases at a constant speed with the increase of torque.
The servo is mainly positioned by pulses. Basically, it can be understood that when the servo motor receives a pulse, it will rotate the angle corresponding to a pulse, thus realizing displacement, because, the servo motor itself has the function of sending out pulses, so every time the servo motor rotates at an angle, it will send out a corresponding number of pulses, thus forming a Echo with the pulses received by the servo motor, or a closed loop, in this way, the system will know how many pulses are sent to the servo motor and how many pulses are received at the same time, so that the rotation of the motor can be accurately controlled, so as to realize accurate positioning, which can reach 0. 001mm. 2.
Stepping motor is an open-loop control element stepping motor device that converts electrical pulse signal into angular displacement or linear displacement.
In the case of non-overload, the rotation speed and stop position of the motor only depend on the frequency and number of pulses of the pulse signal, and are not affected by load changes. When the stepping driver receives a pulse signal, it drives the stepping motor to rotate at a fixed angle in the set direction, called'Step angle'
Its rotation runs step by step at a fixed angle.
The angular displacement can be controlled by controlling the number of pulses, thus achieving the purpose of accurate positioning;
At the same time, the speed and acceleration of the motor can be controlled by controlling the pulse frequency, thus achieving the purpose of speed regulation. 3.
Ordinary Motors ordinary motors are more Motors in our flat time, electric toys, razors, etc.
This kind of motor has the characteristics of too fast rotating speed and too small torque. Generally, there are only two pins, and the positive and negative poles of the battery are connected to the two pins to rotate, then the positive and negative poles of the battery are connected to the two pins in the opposite direction. 4.
Geared motor geared motor is a common motor with a reduction gearbox, which reduces the rotation speed and increases the torque, making the common Motor have a wider use space. 5.
Steering gear the steering gear is mainly composed of a shell, a circuit board, a coreless motor, a gear and a position detector.
The working principle is that the receiver sends a signal to the steering gear, judges the rotation direction through the IC on the circuit board, then drives the coreless motor to start rotation, and transmits power to the swing arm through the reduction gear, at the same time, the position detector sends back the signal to determine whether it has reached the positioning.
The position detector is actually a variable resistor. When the steering gear rotates, the resistance value will also change. The angle of rotation can be known by detecting the resistance value.
The steering gear specifications provided by the manufacturer will include the overall dimensions (mm), Torque (kg/cm), Speed (Seconds/60 °), Test voltage (V)And weight (g)And other basic information.
The unit of torque is kg/cm, which means that an object weighing several kilograms can be lifted at a length of 1 cm of swing arm.
This is the concept of the Force arm, so the longer the length of the swing arm, the smaller the torque.
The unit of speed is sec/60, Meaning the steering gear rotates 60 °The time required.
