- 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).
Basic principles of stepping motorsHow it works:Typically, the rotor of a motor is a permanent magnet, and whencurrentflows through the stator winding, the stator winding produces a vector magnetic field. This magnetic field rotates an angle, causing the rotor to rotate an angle such that a pair of magnetic fields of the rotor align with the magnetic field of the stator. When the vector magnetic field of the stator rotates an angle, the rotor also rotates an angle with this magnetic field. For each electric pulse input, the motor advances one step angle. The output angular displacement is proportional to the number of input pulses, and the speed is proportional to the pulse frequency. By changing the order in which the windings are energized, the motor can be reversed. Therefore, the rotation of a stepper motor can be controlled by controlling the number of control pulses, the frequency of the pulses, and the order in which the phase windings of the motor are energized.
