Speed 120v,3420rpm 60V 17000rpm
For 120V DC
1. 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.
