ABB-QABP Series Motor Features and Benefits

Introduction: Among ABB's many types of motors, QABP's variable speed three-phase asynchronous motors have been widely used for their high performance, reliability, flexibility, and noise.

QABP series motors are designed using computer-aided design techniques. The motor uses a corona-resistant composite enameled wire and uses ABB's proprietary technology to reduce or eliminate shaft currents, significantly reducing bearing failures. The motor has a reasonable design and can be matched with the same type of frequency conversion device at home and abroad, with strong interchangeability and versatility.

This series of motors can be widely used in light industry, textile, chemical industry, metallurgy, machine tools and other industries that need speed control rotating devices, is an ideal speed control power source.

I. Outstanding features of the QABP series

* Frame number: H71~H355

* High reliability, ensuring continuous and smooth operation of equipment, low failure rate, and reducing maintenance costs;

* Flexible design, able to install a variety of accessories according to customer requirements and special design;

* Standard imported deep groove ball bearings, so that the bearing has a higher bearing capacity, the use of the service life has been extended;

* The motor anti-corrosion ability is strong, can run normally under the harsh environment, can provide the higher grade anti-corrosion ability according to the customer's request;

Second, QABP mechanical design

* Fully-enclosed fan-cooled design, standard protection class IP55, can also provide IP56 or IP65;

* Flexible entry mode, the junction box can be installed on the top, right side or left side of the motor;

* 71~132 motor terminal box can rotate 4*90 degrees, 160~355 motor terminal box can rotate 2*180 degrees, all easy to be modified;

* Powerful conversion ability, the motor has a variety of optional configurations for different environments and applications, such as higher protection class, insulation class, oil lubricated device, dust protection, sealing ring, protective cover and so on.

Third, why choose QABP frequency conversion motor

Some customers will ask, many standard motors mentioned in the description can also be connected to the inverter for speed control, why do we still need a special frequency conversion motor? Xiaozhuo to tell you, standard motor in a certain frequency range if you use the inverter speed, the frequency range, the motor voltage and power are limited, can not reach the frequency range of 5 ~ 100Hz, can not achieve variable speed operation Only use a special inverter motor to achieve these functions.

Standard motors do not take into account the need for variable frequency speed control in structural and electromagnetic design. Forcing the use of variable speed drives will jeopardize motor performance and reliability, and long-term use under such conditions will affect the operation of the entire equipment. Causes failures, shutdowns, and even damage.
