Performance comparison of servo motor and stepping motor.
Stepper motor as an open-loop control system, and modern digital control technology has the essential link.
In the current domestic digital control system, stepping motor is widely used HC-KFS23K
With the emergence of digital AC servo system, AC servo motor is more and more used in digital control system.
In order to adapt to the development trend of digital control, most of the motion control system adopts stepping motor or full digital AC servo motor as executive motor.
Although they are similar in control mode (pulse train and directional signal), there are great differences in performance and application.
The use performance of the two are compared. Power: 15kw.
Voltage: 400V.
There are 100% braking torque output in continuous regeneration, which can correspond to the continuous regeneration operation of the pipeline control.
There is no need to install the braking unit for each frequency converter, which can reduce the comprehensive space and reduce the comprehensive cost.
Renewable energy can be used for other frequency converter, excess energy back to the grid, to achieve energy saving. Motor: HA-SH type.
Power: 3.0kw.
Speed: 1000r/min.
The speed regulating motor can be divided into a constant speed motor, a stepless constant speed motor, a stepless speed changing motor and a stepless speed changing motor,
Can also be divided into electromagnetic induction motor, DC motor, PWM variable frequency motor and switched reluctance motor.
The rotor speed of the induction motor is always slightly lower than that of the rotating magnetic field.
The rotor speed of the synchronous motor is not independent of the load size, but is always maintained as a synchronous speed. MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 355KW.
The main circuit of the inverter can be divided into two categories in general: voltage type is the voltage source of the DC converter for AC inverter,
The filtering of the DC circuit is the capacitance; the current mode is the DC conversion of the current source to the AC inverter,
The DC loop filter is the inductor.
Why is the frequency of the inverter voltage proportional to the change?
The electromagnetic torque of any motor is the result of the interaction between the current and the magnetic flux, the current is not allowed to exceed the rated value, otherwise it will cause the heating of the motor.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity.
