Model Analysis | Decoding the SH140/30270 Configuration
1. SH30702S0001137 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).
Dual-speed motor and the difference with ordinary motor and single-speed motorDouble-speedMotor controlWorking principleExplanation Double-speed motor typically has two speeds, usually high speed and low speed. To achieve double-speed control, two controllers or one controller with a changeover switch can be used. A common two-speedmotor control schemeis to use two controllers, one controller controls high speed, and the other controller controls low speed. The externalsignalis used to control which controller starts to achieve two-speed control. The advantage of this scheme is that the control is simple, but it requires two controllers, which is costly. Another common approach is to use a controller and a switch. The controller”s output signal controls the switch to change the motor”s wiring, thus changing the motor”s speed. The advantage of this approach is that it only requires one controller, which is relatively inexpensive. However, the switch needs to be manually operated when switching speeds.
