M2QA/QAD Series Pole Changing Multi-speed Three-phase Induction Motors
By simple switching between the pole pairs, different motor speeds can be achieved.
Electrically derived from M2QA series motors, the M2QA series pole changing multi-speed three-phase induction motors can variate the motor speed by change of the pole pairs.
The mounting arrangements and dimensions are the same as for the standard series motors. M2QA/QAD series motors are extensively used areas such as machine tooling, mining, metallurgical areas, textiles, dying, chemical and agricultural applications. Terminal boxes aremounted either on the top, or on either side of the motor.
The terminal box of motors sizes 80 to 132 can be turned 4 × 90 ° and in motors sizes 160 to 280 rotated 2 × 180 ° . To enable the supply of suitable terminations for the motor, please state cale type, quantity and size when ordering. Polished outward aqqearance
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.
M2QA/QAD motors are designed for high effciency and low temperature rise giving a long service life and reduced running costs. Thermistors Anti-condensation heaters Re-greasing facilities Dust-proof (IP56) Oil seals Non standard flanges Non standard shaft extensions

Cast iron motors - totally enclosed squirrel cage three phase motors
Lubrication
Motor sizes 71-225 are fitted
with bearings that are regreased
for life. For size 250-355 are
equipped with bearing that are
regreasable via grease nipples.
Terminal box
The spacious t erminal box of cast iron makes the
motor quick and easy to connect. The terminal box
of motor sizes 71-132 can be turned 4x90 degrees
and for sizes 160-355 it is possible to turn the terminal box 2x180 degrees. As standard the terminal box is on top of the motor but it is also possible
in some sizes to get it on either right or left hand
side at customers request.
Insulation
Phase insulation and generous
electrical dimensioning give the motor
a high overload capacity. (Suitable for
frequency converter drive)
Endshields, flanges
The endshield and different
variants of flanges are of cast
iron.
Bearings
The motor sizes 71-132 are fitted with
enclosed DDU C3 bearings as standard.
The frame sizes 160-225 are fitted with
enclosed 2Z bearing as standard. Sizes
250-355 have regreasable bearings as
standard. Modern design secure high

Rotor winding
The rotor winding is made of pressure
diecast aluminium, a design that provides
high starting capacity and low noise level.
Low noise level
The high efficiency of the motor
means that a smaller, quieter fan
can be used.
Corrosion protection
Effective corrossion protection
means that the motor can be used
in all environments.
ABB's digital energy management system provides technical support for the transition from "dual control" of energy consumption to "dual control" of carbon emissions
Electrification, digitization, and automation are key measures to achieve carbon neutrality
