The China 6v dc motor factory takes you to know the DC servo motor driving principle and the kind of use
DC servo motor introduction:
DC servo motor, which includes stator, rotor iron core, motor shaft, servo motor winding changer, servo motor winding, speed measuring motor winding, speed measuring motor changer, the rotor iron core by Silicon steel laminate fixed on the motor shaft.
DC servo motor driving principle:
Servo mainly depends on pulses to locate. Basically, it can be understood that when a servo motor receives a pulse, it will rotate a pulse corresponding angle to achieve displacement. Because the servo motor itself has the function of emitting pulses, so the servo motor rotates every time. An angle, It sends out a corresponding number of pulses, so that it echoes the pulse received by the servo motor, or closed-loop, so that the system knows how many pulses are sent to the servo motor and how many pulses are received at the same time, so that, It can accurately control the rotation of the motor to achieve accurate positioning, which can reach 0.001 mm.
DC servo motor specifically refers to DC brush servo motor -- the high cost structure of the motor is complex, the start-up torque is large, the speed range is wide, the control is easy, and maintenance is required, but the maintenance is inconvenient(carbon brush), electromagnetic interference will be generated, there are requirements for the environment. It can therefore be used in cost-sensitive common industrial and civilian settings.
DC servo motors do not include DC brushless servo motors-small motor size, light weight, large output, fast response, high speed, small inertia, smooth rotation, constant torque, and limited motor power. It is easy to realize intellectualization, and its electronic phase change method is flexible, and it can change the phase of square wave or sine wave. The non-maintenance of the motor does not exist in the case of carbon brush loss, high efficiency, low operating temperature, low noise, small electromagnetic radiation, long life, can be used in various environments.
