Introduction：
YZ10
YZ10 DC motor is a separately excited high
power DC motor designed for electric drive oil drilling machine in the top drive
unit. It is the powerful top drive motor at present in China.The international
advanced technology has been adopted in it such as Kapton insulation process,
main pole coils formed by hot pressing, pressed and welded frame, spiral slot of
commutator, reacting brush holder, wire banding, etc. The motor's main features
are: vertical double shaft extension structure, plus pressure explosion-proof,
direct thermometry, directive tachometry, heavy current, high torque, wide range
constant power speed regulating, free maintenance, high universality, efficiency
and reliability. Both of the data and performance can reach the standard of
imported oil drilling motor. The oil drilling motor can be used instead of the
imported one. The motor can also function as rotary table motor or winch motor
of DC electric drive drilling machine.
