Don’t wait for the future – it’s here NOW!

High Performance (HP) is a generation of permanent magnet (PM) synchronous motors that achieve Super Premium IE4 and Ultra Premium IE5 Efficiency level, combining the electrical design of brushless servo motors with the mechanical design of AC induction motors. 

 

With higher efficiencies than standard AC induction motors, the HP range also enhances the power/weight ratio, thereby allowing for significant size and weight reductions down to 50%.

 

Thanks to the torque and the high efficiency, available through the complete speed range, the HPS series is targeted to both quadratic torque applications, typically in HVAC, as well as to constant torque applications like material handling, air compressors and vacuum pumps. These applications require high performances in continuous operation under variable speed, reducing the operating cost and weight/size of the system.

 

The motor range is based upon Surface Mounted Permanent Magnet (SMPM) design. PM motors typically use rare earth elements such as Samarium and Neodymium in the construction of the magnet elements.

 

Furthermore, in order to address market challenges and multiple application needs, Lafert have introduced for specific projects a cost effective Interior Permanent Magnet (IPM) design and Surface Mounted Permanent Magnet (SMPM) design and introduced different magnet elements more readily available, without applying rare earth magnets.

 

The complete range 0.37 kW to 37 kW are supplied as stand-alone motors (HPS range) to be controlled by a separate drive or as motor/drive integrated units (HPI range), specifically designed for their energy saving potential. 

 

Lafert also offer flexibility in terms of design, customising the active and mechanical parts of the motor to suit specific customer requirements.
