Model Analysis | Decoding the SH140/30270 Configuration
1. SM070/60/020/P0/44/M1/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).
The speed control mode is different: the speed of the induction motor is generally realized by frequency converter; while the speed of the permanent magnet synchronous motor can be realized by changing the power frequency and the number of pole pairs. Different running stability: induction motors may experience speed fluctuations and stalling when the load suddenly changes; while permanent magnet synchronous motors have faster response speeds for speed and torque when the load changes, and the operation is more stable. Different costs: Induction motors, due to the use of traditionalelectromagnetic inductionprinciples, do not require permanent magnets and therefore have a relatively low cost; while permanent magnet synchronous motors require permanent magnets and are more expensive. In summary, induction motors and permanent magnet synchronous motors exhibit significant differences in their operating principles, torque characteristics, speed control methods, operational stability, and cost, making them suitable for different applications and requirements. Induction motors are capable of providing large torque starts and adapting to load changes, making them suitable for a variety ofmechanical equipment and household appliances; permanent magnet synchronous motors, with their fast response and high operational stability, are suitable for applications with high performance requirements, such as wind power generation, electric vehicles, etc.
