30 HP CG IE4 MOTORS, 1500 rpm

Product Details

APEX series motors are having excellent aesthetics and designed in such a way that provide user with flexibility in the position of main terminal box; on top as standard or on left or right side of the motor as an option. In aluminum range motors( up to 7.5 kW) : By simply changing the position of the feet, user is able to convert right, left or top terminal box position and by changing the standard end shield user can change it for flange and face version. Low vibration and low noise  APEX series motors are designed with and to have low vibration and noise , high torque with smooth acceleration throughout the life of the motors, these features makes our motors the most preferred choice for various industrial applications. Inverter Duty application APEX series motors are suitable for inverter duty applications*, our insulation system provides key benefit of increasing the dielectric resistance of the motor windings, enabling operation with variable frequency drives. For protecting the motors from bearing currents a phenomena which is generally observed in frames IEC315 S/M and above, CG recommend/provide insulated bearing for VFD compatible motors. *for details on VFD operation, please contact CG sales INTRODUCTION Other designed features offered CG APEX SERIES Frames Frames (cast iron range) are constructed using high grade cast iron, ribbed externally to ensure maximum heat dissipation. All components are machined on CNC that ensures co-planarity of machined surfaces. All components are completely enclosed and air is forced over the stator body by fan, mounted on the shaft and protected by a cowl. The feet are integrally cast with the body. This ensures sturdiness and resistance to vibrations.  Cooling system  APEX SERIES motors are specially design to achieve improved air flow over the motor frames and to maintain low operational temperature and assuring extended life of the motor. APEX SERIES motors comes up with improved aerodynamics that provide effective air flow and minimizing losses due to the recirculation of air between the fan and fan cover. Shaft and Bearings The shaft is of high grade steel and of appropriate diameter to withstand the bending and torsional stresses. All shafts are ultrasonically tested for any minor flaw in the material. Shafts are machined to extreme fine limits to ensure fit and interchangeability of bearings. The motors are provided with single shaft extension, we comply to the general requirement of IEC60034, We can offer motors with special shaft on request, ◊ Nonstandard diameter and length ◊ Taper shaft with threaded end ◊ Double shaft extension Terminal box CG Apex series motor is fitted with terminal box and gives IP55 degree of protection. The box can be rotated through 360 degree in steps of 90 degree to give cable entry from any of four positions. TB are designed in such a way that provide more space for proper positioning of cable inside terminal box  Standards Description Rotating electrical machine-Rating & Performance IEC 60034-1:2010 IEC 6003430:2008 Rotating electrical machine-IE code for efficiency classes IEC 60034-21:2007 Rotating electrical machine-Determination of losses & efficiency IEC 60034-5:2006 Rotating electrical machine-Degrees of protection IEC 60034-9:2007 Rotating electrical machine-Noise limits I
