"MOTCO" Alternators Specially designed, self-excited /separately-excited and self-regulated in screen protected drip-proof enclosure, available in Single Phase (230V/50HZ) and Three Phase (440V/50HZ) at 1500/3000 RPM, Manufactured under strict quality control, Specially designed heavy-duty with low temperature rise , better air circulation and greater efficiency with + / - 5% Voltage regulation.
Generators are of drip-proof with rotary field type and adopt harmonic excitation system, easy operation and maintenance. |
Generators are three-phase, four-wire type, adopting star connection with neutral point. The rated line voltage is 400V, phase voltage 230V, frequency 50Hz. power factor 0.8(lag). We can provide 60Hz and the other voltage's generator according to the customer's request.
They can be coupled with a prime mover directly or through v-belt making right or reverse continuous rotation at the rated speed. When the rotation speed of prime mover changes 3% or so and load varies in the range of 0~100% cos j 0.8~1.0, the generators offer constant voltage, when sudden change (increase or decrease) of load, the generator will soon return to their normal working state, at the same time, without any starting device the generator can directly start an unloaded squirrel cage induction motor.
DC GENERATORS
"MOTCO" DC Generators are available in Shunt/Series/ Compound versions. Specially designed, self-excited /separately-excited and self-regulated in screen protected drip-proof enclosure, available in Single Phase and Three Phase output at 1500 RPM, Manufactured under strict quality control, Specially designed heavy-duty with low temperature rise , Copper graphite carbon brushes, better air circulation and greater efficiency with + / - 5% Voltage regulation.
kw Ratings -0.18kw till 30kw.
A separate exciter motor can also be coupled to adjust the excitation of the Generator under loaded conditions to maintain the output voltage to the desired value. |
