Model Analysis | Decoding the SH140/30270 Configuration
1. SM140/30/370/P0/40M1/B1/01 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).
High-speed performanceIt is well known that servo motors operate at higher speeds than stepper motors. This truly means that a servo motor will output more torque than a stepper motor at the specified RPM. This difference in torque performance is due to a difference in pole count as well as the difference in inductance between the windings of a servo motor and a stepper motor.The number of steps also affects how many times the motor winding needs to advance to make the motor rotate one full revolution. For a servo motor, it may only take 12 “steps” to make a full revolution. However, for a 2-phase stepper motor, it requires 200 “steps”. At low speeds, this does not make a significant difference. However, at high speeds, the driver will not be able to fully energize the winding. Sincecurrent is proportional to torque, torque will decrease at high speeds.The performance difference between a stepper motor and a servo motor is best reflected in their speed-torque curves. This is an example of a comparison between a stepper motor and a servo motor of the same frame size.NEMA 23 stepper motor 200 watts (1/4 horsepower) 60 mm servo motor
