The 8MSA3L servo system (servo mechanism) is an automatic control system that makes the output controlled quantity such as the position, orientation and state of the object follow any change of the input target (or given value). The servo mainly depends on the pulse to position, basically can be understood in this way, the servo motor receives a pulse, it will rotate the corresponding Angle of a pulse, so as to achieve displacement, because the servo motor itself has the function of transmitting pulses, so each rotation Angle of the servo motor will emit the corresponding number of pulses, so that the pulse accepted by the servo motor echoes. Or closed loop, so that the system will know how many pulses are sent to the servo motor, 8MSA3L and how many pulses are received back at the same time, so that the rotation of the motor can be very accurately controlled, so as to achieve accurate positioning, 8MSA3L can reach 0.001mm. Dc servo motors are divided into brushed and brushless motors. Brush motor has low cost, simple structure, large starting torque, wide speed regulation range, easy control, and needs maintenance, but the maintenance is not convenient (change the carbon brush), electromagnetic interference, and the environment is required. Therefore, it can be used in cost-sensitive ordinary I industry and civil occasions. Brushless motor small size, light weight, large output, fast response, high speed, small inertia, smooth rotation, torque stability. 8MSA3L control is complex, easy to achieve intelligent, its electronic commutation mode is flexible, can be square wave commutation or sine wave commutation. The motor is maintenance-free, high efficiency, low operating temperature, small electromagnetic radiation, long life, and can be used in a variety of environments.
Features such as Safety Limited Torque (SLT), Safety Speed Observation (SSO) and Safety Lock Test (SBT) are suitable for applications that meet SIL 2/PL d/Cat.3.
The 8MSA3L.E3-E1 has the advantage of safely and reliably limiting the torque applied to the drivetrain, making the mechanical design more cost-effective and minimizing the risk of injury to the operator due to crushing or rolling while operating the machine. The disadvantage is that the price is relatively high and the power factor is low.
