SynchroVERT� IE4 Motors

Our new SynchroVERT� range of IE4 motors combines high efficiency with a host of technologically superior features.

Nipa Agencies 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

Nipa Agencies 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.

Advantages Of SynchroVERT�

Key benefits of our IE4 LSPMS motor include:

• Online starting
• Can operate without a VFD
• Lossless excitation
• High efficiency
• 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.

In other applications, the higher speed results in more output of the product, eg, spinning frames, textile machines, etc.
