Our new products SynchroVERT range of IE4 motors combines high efficiency with a host of technologically superior features. Super Premium IE4 class of efficiency as per IS 12615-2011 and IEC 60034-30-1Line Start Permanent Magnet Synchronous Motor (LSPMSM) technology. Operates without a VFD.Remarkably short payback periods.
Bharat Bijlee has always been a front-runner in providing energy efficient motors and automation solutions that help our customers reduce the life-cycle energy costs of their motor-driven systems.
To complement our portfolio of IE2 and IE3 motors, we now introduce - for the first time in India - our new range of SynchroVERT motors that conforms to the Super Premium IE4 class of efficiency. With a remarkably short payback period, they offer significant savings over IE2 and IE3 motors along with a host of technologically superior features.
Energy Efficient Motors conform to the following standards defined by IEC 60034-30- 1-2014:
Efficiency Class IE1: Standard efficiency
Efficiency Class IE2: High efficiency
Efficiency Class IE3: Premium efficiency
Efficiency Class IE4: Super Premium efficiency
Bharat Bijlee's SynchroVERT is a range of Super Premium IE4 class Line Start Permanent Magnet Synchronous Motors (LSPMSM)*. These motors do not need a VFD for operation, unlike most PMSMs, and can easily replace existing squirrel cage induction motors. They offer significant savings over IE2 motors.
Key benefits of our IE4 LSPMS motor include:
Can operate without a VFD
High power factor at all loads
No rotor losses
Runs at synchronous speed
Suitable for applications with constant torque below synchronous speed and constant HP above synchronous speed. Multiple motors run at exactly the same speed without VFDs: this eliminates speed encoders for feedback control. Starting currents are lower than in IE2 motors; starting torque values are similar to IE2 motors.
As these are synchronous motors, the rated speed is synchronous i.e. 1500 RPM. With this motor, a pump or fan will run at about 3% higher speed and it will give much higher discharge/air delivery. Hence if the pump or fan is already fully loading the motor, it cannot be used unless the impellor is redesigned or it is used along with a VFD drive.
