Q:The laptop's power adapter is broken how much it costs
Notebook adapter only for the general repair 50-100 new general 150-250
Q:Octopus AC Servo motor can be driven with ordinary inverter?
If it is synchronous motor, it depends on whether you choose the inverter is compatible with the synchronization machine, most of the incompatible.
As you said the situation, the motor 8 pole, may be synchronous motor.
Specifically, you can compare the rated speed and rated frequency to see if there is a slip rate to determine whether it is synchronous or asynchronous motor.
Q:How does the variable frequency motor output torque at very low frequencies?
1, to improve the slip of the inverter compensation coefficient
2, to improve the continuous lifting coefficient of the inverter, but the coefficient is too high there will be overcurrent.
3, with no sensor vector control can increase the motor output torque or encoder with the vector control can make the motor at low frequency to achieve the rated output torque.
Q:Laptop power adapter how to detect?
After opening to see what is burned, Estimated to be insurance and the like
Q:How do I select a drive? Which brand is better
8, drive explosion-proof motor, the inverter is not explosion-proof structure, the inverter should be set in a dangerous place outside.
9, the use of inverter drive gear motor, the use of the gear by the part of the lubrication part of the lubrication control. When lubricating oil is lubricated, there is no limit in the low speed range. If there is a high speed range above the rated speed, there is a risk that the lubricating oil may be used. Therefore, do not exceed the maximum speed allowable value.
10, the inverter drive winding rotor asynchronous motor, most of the use of existing motor. Winding motor and ordinary squirrel-cage motor compared to the winding motor winding impedance is small. Therefore, it is prone to overcurrent trip due to ripple current, so a frequency converter larger than the normal capacity should be selected. General winding motor for flywheel torque more occasions, in the set acceleration and deceleration time should pay more attention.
Q:What is the number of parameters of the motor frequency of the Siemens inverter?
Siemens inverter motor pole number parameter code is r0313 motor pole pairs. Note that the number of pole pairs.
Q:380V motor addition to the inverter, but also how to change its speed?
Rotary motor rotor series resistance adjustable speed.
4. Change the slip electromagnetic speed (slip motor)
Q:The emitter E of the inverter inverter module and the AC output U are not directly connected together
Pairs of modules are connected in a phase branch
The phase output is derived from the neutral point between the modules
Q:Three motors, if coupled with the governor speed, is it necessary to add the inverter?
Second, the variable speed: change the way the stator winding wiring to change the cage motor stator pole pairs to speed.
Q:What is the maximum speed adjustable for a 4-stage motor with a rated frequency of 50Hz / 60Hz?
Motor speed and frequency of the formula
N = 60f / p
In the above formula
N - the speed of the motor (r / min);
60 - per minute (seconds);
F - power frequency (Hirsch);
P - pole pairs of motor rotating magnetic fields.
China provides the standard power frequency f = 50 weeks / second, so the rotation of the magnetic field of the size of the theoretical diameter only with the magnetic pole. The number of pole pairs is large, and the rotational speed of the rotating magnetic field is low.
