Model Analysis | Decoding the SH140/30270 Configuration

1. SM140/30/120/P0/45/S1/B0 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).

Working principleThe working principle of an induction motor is based onelectromagnetic induction laws and the Lorentz force and other physical principles. When the motor is powered, a magnetic field is generated within the coil, resulting in electromagnetic induction between the stator and the rotor. This produces torque, causing the rotor to rotate and driving the connectedmechanical device to operate.Features(1) Stability: WFM motors operate at a fixed frequency, providing good stability and reliability. Their speed and power output remain relatively constant, making them suitable for applications with stable loads.(2) Low cost: WFM motors have a relatively low manufacturing and maintenance cost since they do not require additional electronic equipment to regulatepower frequency.(3) Wide applicability: Since WFM motors have become an industry standard, many devices and machinery are designed to use them without the need for additional modifications.Applicable scenariosIndustrial frequency motors are suitable for many daily and industrial applications. For example, electric fans, refrigerators, and washing machines all use industrial frequency motors as power sources. These devices usually have stable workloads and fixed operating requirements, so the industrial frequency motor is the most appropriate choice.
