Description
YR
series (IP*3) three-phase asynchronous motors slip-ring
motor is shielded, YR**0 latest design of low-voltage high-power
motor. Motor power rating and mounting dimensions in accordance
with IEC international standard shell protection grade IP*3,
cooling method IC*1, continuous working system (S1). Applicable to
non-flammable, explosive, corrosive gas and cleaner, more natural
spaces.
This series motors can be smaller
starting current, larger starting torque and speed can be adjusted
within a certain range, can be widely used in: (1) greater than
squirrel-cage rotor motor starting torque;(2) feed line capacity
sufficient to start squirrel cage rotor motor; (3) frequent
start-up time is longer and start; (4) requires a small area
governor; (5) together into electrical axis synchronous
transmission and other occasions.: Winch, hoist, wire drawing
machine, compressor, ball mill, squeezed sugar machine, winches,
transmission with heavy load starting, short-term load operation of
machinery and equipment.
This series of motors has advantages
of high efficiency, strong overload capacity, low noise, small
vibration, reliable structure, good looks, especially for exports,
and can be imported equipment, interchangeable. This series motor
is used for to replace JR JR2, JR3 old series slip-ring motor
upgrade product, to achieve energy saving and improve the technical
level of supporting host and run the ideal product
reliability.
Motor using a Class B or Class F
insulation, rated voltage of **0V (can also be made of **0V), rated
frequency of *0Hz stator delta connection (**0V Y connection) and
rotor for Y connection. Construction and mounting of the motor IMB3
(base with foot, end cap flange, horizontal). Stator and outlet:
H******5 side of the outlet; H******0 top qualifying.
This series motor full voltage direct
start, but starting rotor circuit must be connected to starting
rheostat or frequency sensitive resistor, normal operation should
start after the completion of three rotor winding lead wire
shorted. Allowed in the collector ring or the brush holder
(including the three lead line) directly shorted starter use. The
figure below shows the starting rheostat wiring schematics (for
reference).
