Model Analysis | Decoding the SH140/30270 Configuration
1. SH31001P01A2020 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).
Increase the voltageIn the form of energy conversion in the motor, the loss of electrical energy is manifested as copper loss, and its influencing factors includecurrentandresistance. If the designer finds that the copper loss is too large, the simplest solution is to increase the working voltage. For example, for a motor with an input power of 500W, if its working voltage is 10V, it means that the current must be 50A, because the input power is the product of voltage and current. However, if we increase the voltage to 100V, the current only needs to be 5A. Since the relationship between copper loss and current is quadratic, the copper loss will be reduced by 100 times after the voltage is increased. This also explains why the working voltage of recent electric vehicles tends to develop to 800V.Improve the slot utilization rate of ****When it is not possible to increase the voltage, we often need to find ways to reduce the resistance. The most straightforward strategy is to increase the cross-sectional area of the conductor. In the field of motors, this has led to discussions on how to improve slot fill factors, and has resulted in new technologies such as flat angle winding wires, which are varnished wires designed to achieve the goal of improving motor efficiency.
