A new High-Performance motor intended for the OEM market that offers significant savings on running costs and space requirements that can be engineered to match customer’s applications has been introduced by Lafert.
Savings on operating costs are substantial since the motors are far superior compared to standard AC induction motors enabling significant frame size and weight reductions.
The new Lafert ‘High Performance’ motor (Hp motor) combines the technology of both brushless Permanent Magnet Servo Motors and conventional AC induction Motors. The ability to do this is facilitated by the fact the Lafert group has both Servo and AC induction motor “know how” in-house.
By combining these technologies, substantial efficiency advantages over conventional Ac induction motors, including IE4*, are achieved. The efficiency is superior across the whole speed range.
The enhanced performance characteristics of the HP motor also permit Lafert to offer smaller frame size solutions and weight savings of around 50%.
All these combined features enable engineers to achieve compact efficient motor solutions, particularly for such applications involving pumps, fans and compressors that are substantially more compact, lighter in weight and less expensive to operate. All these benefits are provided from one development source due to Lafert’s in-house technology and the ability to harness the best from proven components such as the AC induction motor’s standard stator and the surface-mounted permanent magnet rotor from the brushless servo motor.
The High performance motor can be used with a standard drive when fitted with an appropriate transducer but, ideally, it should be used in conjunction with a sensorless drive to maximize the motors performance and superior efficiencies for the specific application.
Also, mechanical adaptation of the motor is often needed, so Lafert offer customization to enable integration of the motor deeper into the application.
Lafert can deliver drives controlling stand-alone PM motors (HPS range) or drives integrated into the PM motors (HPI range).
