If CD series driver is used, zero command can be used to enable the driver. The current flows in from the C end of stator system group and out from the B end to generate a stator magnetic field with the same number of poles as the rotor magnetic field. The strength of the magnetic field can be set by zero. Set zero = 5 (5% of the continuous current of the motor), and slowly rotate the rotor by hand for a circle. Whenever the magnetic pole of the rotor is aligned with the magnetic pole of the stator (same or different), there will be a pause. If the rotor turns with 2p stops, the pole number of the motor is 2p.
If you use a drive without a rotor zero command, such as S600 / S300, you can set the drive to serial current mode.
No bending moment is generated, so that the axial load is minimized. The function and use of the coupling of the miniature motor of the plum shaped coupling, this time I finally understood the purpose: applicable to servo system, spindle drive, lifting platform, machine tool drive, gearbox motor. Advantages: compact, no backlash, three different hardness elastomer, can absorb vibration, compensate radial and angular deviation. The motors of structural medical devices are simple in wholesale, easy to maintain, easy to check, maintenance free, oil-resistant and electrical insulation, operating temperature is 20 ℃ - 60 ℃; the plum shaped body has six and eight lobes; the fixed way has key slot selection. The function and use of the micro motor coupling of 0 curved tooth coupling, this time finally understood the use: for flexible transmission. Advantages: strong correction ability in axial, radial and angular direction; good mechanical properties, high temperature resistance (+ 100 ℃), low temperature embrittlement; good electrical insulation characteristics.
