| Alternating current motor-->YJ series |
| |
|
General
This series motor is used for alternating current
frequency conversion oil drilling machine. It is also
used for electric rolling plate of driving driller, winch,
mud pump and equipments which need dragging. Its mounting
size coincides with the direct current driller at home
and abroad. This series motor adopts advanced insulation
structure and special anti-broken measures. This helps
motors start with constant torque in low frequency and
have wide constant output range in order to satisfy the
needs of coincidence of load starting and high speed acceleration.
It has good ventilation, high efficiency and stability,
also free from repair.
Briefing
of construction
The series motors are three-phase squirrel frequency
conversion timing asynchronous ones whose structure is
horizontal, single shaft, and double bearing brace. The
shaft is 1:9.6 cone and equipped with oil scupper of hydraulic
pressure. The motor is protective forced ventilation,
self-equipped blower, the cooling air comes from non-driving
end and exhausts from driving end cap. The blower can
be installed on top or in side according to customers’
request. There is also coding connection as customer requires.
