Model Analysis | Decoding the SH140/30270 Configuration
1. SM140/30/370/P0/40M1/B1/01 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).
Stepper motors generally do not have overload capability. AC servo motors have strong overload capability. Take Panasonic AC servo system for example, it has the capability of speed overload and torque overload. Its maximum torque is three times the rated torque, which can be used to overcome the inertial torque of the load at the moment of startup. Stepper motors, because they do not have this overload capability, often need to select a motor with a larger torque in order to overcome this inertial torque when selecting a model, but the machine does not need such a large torque during normal operation, resulting in torque waste.Five, different running performanceThe control of the stepping motor is open-loop control, and it is easy to appear stepping loss or stall when the starting frequency is too high or the load is too large, and it is easy to appear overshoot when the speed is too high at stop, so in order to ensure its control accuracy, the acceleration and deceleration problems should be handled well. The AC servo drive system is a closed-loop control, and the drive can directly sample the feedback signal of the motor encoder, and the internal composition of the position loop and the speed loop, generally will not appear stepping motor stepping loss or overshoot, and the control performance is more reliable.
