Model Analysis | Decoding the SH140/30270 Configuration

1. SM140/30/120/P0/45/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 difference between high-speed motor and low-speed motorHigh-speed motor：High-speed motors generally refer to motors with a speed exceeding 10,000r/min. They have the following advantages: First, due to the high speed, the power density of the motor is high, and the volume is much smaller than ordinary power motors, which can effectively save materials. Second, it can be connected to the prime mover, canceling the traditional speed reduction mechanism, with high transmission efficiency and low noise. Third, due to the small rotational inertia of the high-speed motor, the dynamic response is fast. So let”s see why the factors of choosing high-speed are.1、By deceleration, it can meet the requirements of low speed with better performance;2、High-speed motor control High precision, the same 10r/min speed error is 0.1% for a 10000r/min high-speed motor and 10% for a 100r/min high-speed motor;3、Easy to make, relatively small volume, relatively low price;4、The operation is little affected by load changes. The same magnitude of load change acts directly on the low-speed motor, while for the high-speed motor with N times reduction, the force is only 1/N.
