Model Analysis | Decoding the SH140/30270 Configuration
1. SH30702P11A2000 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).
Technical Features | Precision Control Meets High Efficiency
1. Core Performance Parameters

Stepper motor Brushed motor Brushless motorRotating method Throughdriving circuitthe armature winding phases (two-phase, three-phase, five-phase) are excited in the order decided. By the sliding contact type of rectifying mechanism through the brush and commutator, switch the armaturecurrent. by using magnetic pole positionsensorsandsemiconductorswitches instead of brushes and commutators to achieve brushless.Driving circuit Need Not needed NeedTorque The torque is relatively large. (Especially the torque at low speeds) Large starting torque, torque is proportional to armature current. (The torque is relatively large at medium to high speeds)Rotating speed Proportional to the frequency of the input pulse. There are slip zones in the low-speed range. Proportional to the voltage applied to the armature. The speed decreases as the load torque increases.High-speed rotation High-speed rotation is difficult (need to slow down).
