1. SM100/50/030/P1/45/S1/B0 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).
Three, the working principle of brushless and brushed motorsThe working principle of brushless motorBrushless motors use semiconductor switching devices to achieve electronic commutation, replacing traditional contact-type commutators and brushes with electronic switches. Inside the motor, a position sensor (such as a Hall sensor) is used to detect the position changes of the permanent magnet rotor, and the current switching of the stator winding is controlled accordingly. This electronic commutation method gives brushless motors higher reliability, lower mechanical noise, and less maintenance requirements.The working principle of brushed motorThe working principle of brushed motors is based onelectromagnetic induction. When the motor is working, the brushes and the commutator are in constant contact and friction, playing a role in conductivity and changing phases during rotation. By changing the position of the brushes, the direction of the angle between the magnetic poles of the stator and the rotor can be changed, thus changing the rotation direction of the motor. Brushed motors have the advantages of fast starting, timely braking, stable speed regulation, and simple control, but their brush wear problem limits their service life.
