Model Analysis | Decoding the SH140/30270 Configuration
1. SM100/40/080/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).
To sum up, when the air gap of the induction motor increases, it leads to an increase in the leakage reactance, thereby affecting the efficiency and performance of the motor. Therefore, in the design and manufacturing of induction motors, it is necessary to control the size of the air gap. The difference between induction motor and permanent magnet synchronous motor Induction motors and permanent magnet synchronous motors are two different types of AC motors, and their differences are as follows: Working principleDifferent: The induction motor uses the alternating current in the stator winding toinducecurrent in the rotor, generating torque; while the permanent magnet synchronous motor uses the alternating magnetic field generated by the permanent magnet and the stator winding to induce electromagnetic torque in the rotor, thus achieving operation. Different torque characteristics: The induction motor can provide a large torque at startup, but the speed drops and the torque drops when the load is large, and there is a slip in speed; while the torque of the permanent magnet synchronous motor is proportional to the speed, the speed change is small, and there is no slip.
