Model Analysis | Decoding the SH140/30270 Configuration

1. SM140/30/120/P1/45/M1/B0/01 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).

5. Comparison between brushless and brushed motorsPerformance comparisonBrushless motors offer superior efficiency, noise levels, and reliability compared to brushed motors. The operational efficiency, low-speed torque, and speed accuracy of brushless motors are generally better than their brushed counterparts, and they require minimal additional maintenance. However, brushless motors are relatively more expensive, and their controllers can be prone to failure. Brushed motors, on the other hand, remain competitive in specific applications due to their low cost, simple control, and quick starting capabilities.Life span comparisonThe brushless motor has a longer service life than the brushed motor. The brushless motor can operate continuously for about 20,000 hours, with a normal service life of 7-10 years; while the brushed motor can operate continuously for about 5,000 hours, with a normal service life of 2-3 years. This is mainly due to the fact that the brushless motor has no brush wear.Six, ConclusionBrushless motors and brushed motors each have their unique principles of operation, functions, and application scenarios. Brushless motors, with their high efficiency, low noise, and high reliability, are widely used in various fields; while brushed motors maintain competitiveness in specific areas due to their fast starting, timely braking, and low cost. When choosing a motor, it is important to consider the specific requirements and application scenarios comprehensively.
