Self coupling voltage regulator and rectifier bridge (1000V 3A) + high voltage capacitor (450V 1000uf or greater). This is the power of heavy weight inconvenient movement. 2. 220v+ AC thyristor voltage regulating and rectifier bridge (1000V 3A) + high voltage capacitor (450V 1000uf or greater) This motor is great for diy miniature bench drill micro lathes grinding sawing and other purposes 1. Weight: 0.53-0.58kg rated voltage 120V 3420rpm (other voltage can be calculated in proportion such as 60V 1700rpm). When in use use electric power 220v+ rectifier and light load as power (note the speed of about 6000rpm). 2. Front and rear ball bearing steel front cover stamping molding structural strength and light weight. 3. The steel shell thickness 1.8mm magnet thickness 6.5mm the caliper sounding bar to go in steel sheet will be attracted to the bending magnet magnetic quite good. Strong magnetic is the guarantee of DC motor torque an important factor in the efficiency of the. 4. Very bright copper brush. No oxidation traces (light carbon footprint on the picture is formed after testing). Looks like gold. 5. Brush although built-in but can be replaced a very important advantage of built-in brush solid and reliable easy to damage the external transport in. 6. The back cover integrated brush bases and anti SMC EMI magnetic core inductance voltage sensitive resistor (remove burr burr high pressure pressure can be generated by the motor itself or grid) temperature fuse (this is not self recovery) 7. Front cover sheet steel stamping front and rear ball bearing and no series shaft and bearing design with a clamp spring no mobile space the rotor can not move. The output axis 8mm axis length of 43mm plus the taper connecting sleeve and drill chuck is also a very good micro drill. 8. Coil resistance 160 euro resistance to current = voltage / coil resistance. For example 120V resistance to current =0.8A if the resistance to turn the motor is a resistance the heating power =90W so temperature rises quickly if not in time to stop the temperature fuse cover will fuse or coil paint burn short-circuit.
