Rexrox servo motor MAD100B-0250-SA-C0-AH0-05-N1

Servo motor refers to the engine that controls the operation of mechanical components in the servo system, which is a supplementary motor indirect transmission device. The servo motor can control the speed, the position accuracy is very accurate, and the voltage signal can be converted into torque and speed to drive the control object. Servo motor rotor speed is controlled by the input signal, and can react quickly, in the automatic control system, used as an executive component, and has a small electromechanical time constant, high linearity characteristics, the received electrical signal can be converted into the angular displacement or angular speed output on the motor shaft. Divided into DC and AC servomotor two categories, its main feature is that when the signal voltage is zero, there is no rotation phenomenon, and the speed decreases with the increase of torque.

The advantages and disadvantages of electric servos are as follows:

MAD100B-0250-SA-CO-AHO-05-H3 Advantages. High precision, can achieve high precision motion control; Good high-speed performance, suitable for high-speed movement and frequent start-stop occasions; Strong adaptability, sensitive to environmental changes; Good stability, will not produce a step similar to the stepper motor running phenomenon; The dynamic corresponding time of motor acceleration and deceleration is short; Low heat and noise.

Disadvantages. The cost is higher; It is difficult to debug, and engineers with high technical level are required to fine-adjust the controller, encoder, sensor, etc., and the debugging period is long.

The difference between DC motor and servo motor is as follows:

Different structure: MAD100B-0250-SA-CO-AHO-05-H3 DC motor is usually composed of rotor, stator, brush, armature and other components, is a simple motor structure. The servo motor is composed of motor body, encoder, controller and other components, the structure is more complex, but also more precise.

The working principle is different: when the DC motor is working, the magnetic field of the electromagnet will interact with the magnetic field inside the armature, thereby driving the armature to rotate. The servo motor will be based on the signal of the encoder, through the controller for fine control of the motor, so that its speed and position to reach a predetermined value.

Different application scenarios: MAD100B-0250-SA-CO-AHO-05-H3 DC motor has the advantages of simple structure, wide speed range, easy control, etc., suitable for low cost and high efficiency application scenarios. For example, DC motors commonly used in mechanical structures such as belt drive and gear drive. The servo motor has the advantages of high precision, strong reliability, fast response speed and so on, which is suitable for high demand application scenarios. For example, servo motors are often used in intelligent robots, precision machining equipment and other fields.
