New permanent magnet motors

Dyneo+ permanent magnet motors from Nidec Leroy-Somer are said to be an attractive solution for machine and system builders keen to reduce refrigeration costs

New permanent magnet motors

Nidec Leroy-Somer says that its latest development, the Dyneo+ range of IE5 synchronous reluctance permanent magnet (PM) motors, offers multiple energy saving advantages for driving screw compressors, piston compressors, circulation pumps and condensers at either fixed or variable speed.The company has just launched its new Dyneo+ synchronous reluctance PM motor, ranging from 11kW to 500 kW and suitable for speeds of up to 4500 rpm. Specifically designed for variable speed, this motor is claimed to offer an economic solution for industrial refrigeration applications.

Dyneo+ motors are designed to operate exclusively with a variable frequency drive, allowing them to adapt to the speed of the machine being run and improve its performance when operating in overspeed. Nidec Leroy Somer says that this provides the benefit of additional refrigeration capacity for a given device, thereby avoiding having to start up another compressor during a production peak. Moreover, the Dyneo+ solution is claimed to enable the optimisation of the number of compressors for a given installation. Delivering precise speed and torque control in sensorless mode, it offers constant torque over wide speed range with no derating or forced ventilation.

Nidec Leroy-Somer states that it has developed the Dyneo+ range based on the mechanical platform of its IMfinity® induction motors, and that the use of proven components makes these new motors extremely durable. With low  rotor losses, the magnetic synchronous reluctance technology reduces maintenance costs, in particular by extending the lubrication intervals. Compact and IEC interchangeable with aluminium or cast-iron housings, the motors are available in IP55 or IP23 versions and are said to be a straightforward retrofit in existing installations. Dyneo+ is connected to the Systemiz interactive application, which provides a wide variety of digital services, including instantaneous access to all the product literature, and easy and intuitive drive setup by simply scanning the QR code on the nameplate.

Made in Europe and with low carbon footprint credentials, the Nidec Leroy-Somer says that its Dyneo+ motor is eligible for Energy Savings Certificates, (also known as White Certificates), generating government aid through the energy savings made.
