Application of T44A15-3P contactless in ceramic industry

Lang wind electric technology development Co., Ltd. the production of patent products T44A15-3P,
Specifically for the 1.5Kw three-phase AC motor and design production. Because it is not affected by the adverse environment, anti dust, corrosive gas, switching speed, suitable for wide voltage range, if the voltage is not stable place also can complete the action is accurate, high structural strength, dust-proof, anti moisture, corrosion resistance, the advantages of long service life, fast switching speed, no noise, volume small, no spark, explosion-proof, anti vibration and impact resistance, strong anti vibration.
Application of T44A15-3P is of great significance to the machine import and kiln in ceramic industry, we enumerated the concrete application
A: the lifting motor, baffle motor:
For non contact with long wind, accurate positioning, not for ordinary contactor iron core wear caused by factors such as the lifting frame is high or low, even the program chaos (proximity switch dislocation), little maintenance use, greatly reducing the failure rate.
Two: feeding machine stepper motor and stop the motor is replaced by T44A15-3P converter:
Now many manufacturers in the use of inverter driven here the two motors, this approach is wrong, the reason is the inverter to the acceleration time and deceleration time (at least 0.1s or 100ms), it is lagging behind the operation signal. The two motor is not synchronous operation of stepper motor, often in a stopped state (namely stop, Adobe After step photoelectric after waiting period to stop motor transport again Adobe) it will need to reduce to a halt motor speed to eliminate the impact acceleration time caused by. But when tile gap is very small and continuous over, in the row of bricks (step) will appear when the gap between the large brick, is not conducive to the kiln (easily cause plugging kiln), visible two is contradictory, it is difficult to adjust, or collision or enlarged the gap.
While the application of two T44A15-3P to replace the frequency converter can solve this problem easily, reason is the long wind contactless fast action, without the acceleration time and deceleration time, said the start, stop, as long as adjust once, no matter how Brick interval and the number of connecting wires sent, can arrange consistent, also won't produce collision. Is not affected by the voltage level.
Three: the use of T44A15-3P kiln brick motor and roller table waiting for motor,
Because of long wind no contact with zero conduction, and the on-off without spark, so when in conduction motor coil insulation on the no shock, motor start smoothly, the drive belt or gear has no impact, the service life can be prolonged greatly.
While the ordinary contactor is random without zero switching function, but also can produce sparks in the on-off, so in general contactor on-off often (especially in the near 90 degrees) to produce instantaneous high voltage, the high voltage has a great impact on the motor windings, each time starts and stops. Inconsistency on motor and drag the mechanical impact, accelerate the motor coil heating and mechanical wear.
In addition to the motor use frequency converter is a waste, but also because of acceleration and deceleration time, positioning effect than with no contact to difference, especially when the roller table mechanical resistance small, brick row position often fluctuation.
Four: T44A15-3P motor compressor surrounding
Especially the blanking machine press office, should all use T44A15-3P, is directly controlled by PLC T44A15-3P, without an intermediate relay, such a configuration, the failure rate is the highest blanking machine control cabinet to become the lowest failure rate. Dust the environment is too large, the intermediate relay and contactor is often damaged, see inside large dust and can not be cleaned up, a new electrician for gas then blew it, will be one or two days to the inside of the ordinary contactor to change all over. T44A15-3P don't worry, a year cleaning once is enough.
Feeding system in the ordinary contactor for T44A15-3P and T22A05F auxiliary contacts, the effect is more obvious.
Welcome to T44A15-3P friends message, to explore the use of experience. We would be grateful!
