Answer：The coreless motor belongs to the DC permanent magnet servo control motor, and it can also be classified as a micro motor . The hollow cup motor has outstanding energy-saving characteristics, sensitive and convenient control characteristics and stabl...
Answer：Coreless motors are DC permanent magnet servo and control motors, and can also be classified as micro motors. In terms of structure, it breaks through the rotor structure of traditional motors, and adopts an ironless rotor, also called a hollow cup r...
Answer：U/f control is to change the voltage of the motor power supply while changing the frequency of the motor power supply, so that the magnetic flux of the motor remains constant. In a wide range of speed regulation, the efficiency and power factor of th...
Answer：The power of the motor should be selected according to the power required by the production machinery, and try to make the motor run under the rated load .
Answer：In the manufacture of the motor industry, welded parts require high welding strength, small heat-affected zone, and high welding precision. Compared with traditional welding methods, laser welding has obvious advantages, and has been applied to the w...
Answer：Once the permanent magnet motor loses its magnetism, basically you can only choose to replace the motor, and the maintenance cost is a lot. How to judge the loss of magnetism of the permanent magnet motor, let's look down.
Answer：Working principle of high-efficiency energy-saving motor and frequency conversion energy-saving motor The working principle of the frequency converter: the frequency converter we use mainly adopts the AC-DC-AC mode, first converts the power frequenc...
Answer：Small three-phase asynchronous motors, usually including H80-315MM motors, have large output and wide application. In the total load of the power grid, its electricity consumption is about 40%. The JO2 series motors were popular in the early 1960s. T...
Answer：When the tile lining is seriously separated from the tile bottom, the alloy damage on the surface of the tile lining cannot be repaired by local repair welding, the wear of the bearing gap is too large, and the restoration of the gasket on the joint ...
