Model Analysis | Decoding the SH140/30270 Configuration
1. SM100-50-030-P0-45-S1-B1 Series Designation: SH140
- Represents the medium-to-large power range, with an estimated power output of 0.75kW–3kW.
2. Core Parameter Code: 30270
This code encompasses critical specifications such as speed, torque, and encoder resolution.
For example, it may indicate:
- Rated speed: 3000 rpm
- Rated torque: 2.7 Nm
(Actual values depend on the full parameter set.)
3. Configuration Fields: 0/1/00/00/00/00/00
These digits define additional options, including but not limited to:
- Voltage level
- Protection rating (e.g., IP65)
- Communication protocol (e.g., EtherCAT, CANopen)
- Functional add-ons (e.g., brakes, oil seals).
Compared with direct current servo motors, the main advantages of permanent magnet AC servo motors are as follows: ⑴ There are no brushes and commutators, so they are reliable and have low maintenance and care requirements. ⑵ The stator winding has a convenient heat dissipation. ⑶ The moment of inertia is small, which is easy to improve the quickness of the system. ⑷ It is suitable for high-speed and high-torque working conditions. ⑸ It has a smaller volume and weight for the same power.Servo and stepper motorsServos are mainly positioned by pulses, which can be understood basically. When a servo motor receives 1 pulse, it will rotate the corresponding angle of 1 pulse, thus achieving displacement. Because the servo motor itself has the function of emitting pulses, the servo motor will emit a corresponding number of pulses for each rotation of an angle, which forms a response with the pulse received by the servo motor, or called 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 back. In this way, it is possible to control the rotation of the motor very accurately, thus achieving precise positioning, which can reach 0.001mm.
