Product Features of QA Motors
QA series three phase induction motors are designed and manufactured to meet the most arduous service conditions. The motors are made using high quality materials and workmanship. With proper maintenance these motors will consistently perform well even in the toughest conditions.
1.These motors are built to comply with current International Standards.
International Electro-technical Commission-IEC60034 and IEC60072.
British Standard-BS5000 and BS4999.
Australian Standard-AS1359-2.
German Standard-DIN42673.
EU directives to fulfill European "CE" marking.
2.These motors are built to comply with current National Standards.
GB755(idt IEC 60034-1)
GB10069(neq IEC 60034-9)
Q/JBQS28
3.Mechanical Design
Terminal boxes
Terminal boxes are mounted either on the top, or on either side of the motor. The terminal box of motors sizes 71 to 355 can be turned 4 x 90° to allow cable entry from either side. To enable the supply of suitable terminations for the motor, please state cable type, quantity and
size when ording. Polished outward appearance
The external design of the motors is consistent with the design of the ABB "M2000" family. The frame, cooling ribs, terminal box and fan cover have been reshaped to meet customer's design preference.
4. Electrical Design
Minimum Noise and Vibration levels
Careful attention to design and manufacturing details has allowed International Standards to be comfortably met.
Maximum Degrees of Protection All ABB motors are protected to IP55 as a minimum. Higher levels of protection are available on request. Service and Operating Conditions QA motors are designed to be insensitive to wide supply voltage fluctuations.
Class F insulation offers greater reliablity and security.
Standard motors have Class F insulation, with a Class B temperature rise to offer more reliability and security in operation, through increased thermal margins. High Effciency QA motors are designed for high effciency and low temperature rise giving a long service life and reduced running costs.
5. Special requirements can be supplied on request
Thermistors
Anti-condensation heaters
Re-greasing facilities
Dust-proof(IP56)
Oil seals
