Model Analysis | Decoding the SH140/30270 Configuration
1. SH070/60010/0/0/00/00/00/10/00 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).
Although servo motors and stepper motors both use permanent magnets in their rotors and requiredriver circuitsto operate, they have fundamental differences in design, resulting in performance differences.Motor designStepper motors can be commanded to move to a certain position, stop, and then hold, while servo motors need to be told to “find” the target position viaencoders. The first major difference you will notice is that servo motors require an encoder, which adds length to the motor.The second major difference is the number of poles. The poles discussed here are “magnetic poles,” which can be defined as the north or south magnetic pole on the rotor. These magnetic poles provide specific stable points where the magnetic flux from the stator will interact with the rotor.To understand the difference in pole count between a stepper motor and a servo motor, we need to take a deeper look at the design of each motor. The image to the left shows the construction of a stepper motor, and the image to the right shows a cross-section of the rotor and stator.Stepper motor
