Detailed information
For 1.1 kW to 90 kW, 2-pole and 4-pole motors in S1 duty cycle, the M2QA series meets the CEMEP-EU Class II efficiency standard and delivers excellent energy-saving performance.
Wide-voltage design: up to 690V and applicable to both 50Hz and 60Hz power grids.
Reliable Winding: The winding utilizes insulation materials based on the latest imported technologies, achieving Class F insulation (Class B—80K temperature rise), thereby ensuring a longer service life for the winding.
Strong corrosion resistance protection: The motor is designed with environmental corrosion resistance, ensuring a longer service life.
The bearings feature high load-carrying capacity: The use of deep-groove ball bearings significantly extends the motor’s service life. Cast-iron motors with a center height of 71–250 mm are equipped with lifelong, maintenance-free bearings, while motors ranging from 280 to 355 mm come standard with grease fittings.
Low Noise Level: By optimizing electromagnetic and electrical designs, improving the cooling system, and refining the structural design, the M2QA series ensures an overall low noise level.
Additional winding protection: Winding protection accessories such as PTC thermistors, thermal switches, and anti-condensation heating tapes can be added upon customer request.
2. Mechanical Design
The fully enclosed, self-cooling design, combined with an IP55 protection rating and a heavy-duty construction, along with the use of highly corrosion-resistant cast iron materials, enables the M2QA series motors to perform reliably in a wide variety of environments. The motor’s mechanical structure is exceptionally robust, and motors with a center height of 280–355 mm are standardly equipped with drain holes and plugs.
Flexible lead-out cable directions. The motor junction box can be installed on the top, left, or right side of the motor, and the junction box itself can be mounted in a rotatable manner. For frame sizes 71–132, the junction box can be rotated in 4 × 90-degree orientations. For frame sizes 160 and above, the junction box can be rotated in 2 × 180-degree orientations.
The motor offers a variety of optional configurations to meet different environmental and application requirements, such as higher protection ratings, enhanced insulation levels, dustproof protection, sealing rings, rainproof devices, and more.
