Robot common motor
The ordinary motor, geared motor, stepping motor and servo motor of the servo machine are the micro-motors of direct current. Most of the contacts we also contact are also direct current. The knowledge of the motor is very deep. This article is just for beginners to talk about the various motors commonly used in making robots.
A motor, commonly known as a "motor", refers to an electromagnetic device that converts or transmits electrical energy in accordance with the law of electromagnetic induction. The electric motor is also called (commonly known as a motor) and is represented by the letter "M" (the old standard is "D") in the circuit. Its main function is to generate drive torque. As a power source for electrical appliances or various machines, the generator is represented by the letter "G" in the circuit.
Ordinary motor
The ordinary motor is the motor that we have more time, the electric toy, the razor, etc. This kind of motor has the characteristics of too fast speed and too small torque. Generally, there are only two pins. When the positive and negative poles of the battery are connected, the two pins will turn up, and then the battery will be connected to the positive and negative poles. The motor on the pin will also reverse.
Geared motor
The geared motor is an ordinary motor with a speed reducer, which reduces the speed and increases the torque, making the ordinary motor have a wider use of space.
Stepper motor
A stepping motor is an open-loop control element stepping motor that converts an electrical pulse signal into an angular displacement or a linear displacement. In the case of non-overload, the speed and stop position of the motor depend only on the frequency of the pulse signal and the number of pulses, and are not affected by the load change. When the stepper driver receives a pulse signal, it drives the stepper motor. The set direction is rotated by a fixed angle called the "step angle" whose rotation is performed step by step at a fixed angle. The angular displacement can be controlled by controlling the number of pulses to achieve the purpose of accurate positioning. At the same time, the speed and acceleration of the motor rotation can be controlled by controlling the pulse frequency, thereby achieving the purpose of speed regulation.
