MEPS-compliant motor series

Sunday, 01 June, 2008 | Supplied by: SEW-Eurodrive Pty Ltd


SEW-Eurodrive has extended the DR series of energy-efficient induction motors to 45 kW. The motors will feature an optimised design and include advanced cast-copper rotor technology variants.

The extended DR motor series will include two variants rated to varying efficiency levels — ‘minimum-efficiency’ (DRE) (spanning 0.75 to 45 kW) and ‘premium efficiency’ (DRP) (spanning 0.75 to 37 kW) — enable users to address differing motor efficiency requirements.

The extension to the DR motor range will allow manufacturers to realise energy savings across an increased range of motor applications on the plant floor. Manufacturers will be able to equip larger conveyors, mixers, pumps and materials handling equipment with energy-efficient drive solutions.

The DRE and DRP motors will exceed the minimum energy-efficiency requirements specified in the Australian Standard, AS1359.5:2004 (three-phase cage induction motors — high efficiency and minimum energy — performance standards requirements) and therefore are Minimum Energy Performance Standards (MEPS)-compliant.

The DR series boasts a flexible design with a myriad of options to suit a wide range of applications. The energy-efficient motor is offered with a ‘premium-efficiency’ option which is useful for continuous or long-running drive applications and can minimise energy consumption, reduce operating costs and decrease greenhouse emissions.

SEW-Eurodrive offers more compact copper rotor variants of the DRE and DRP induction motors in addition to the traditional aluminium rotor motors. Using a copper rotor reduces losses in the rotor and consequently allows for increasing the power within one frame size. Copper variants are available at the transition from one frame size to the next.

The DR motor is available in a variety of form factors, including a choice of up to three different brake sizes per motor size and various onboard inverter and starter options. Rated up to IP66, the DR series can be supplied with a wide range of additional features and a variety of mounting alternatives that complement and extend SEW-Eurodrive’s modular drive systems. Additional flexibility can be obtained via various incremental and absolute encoders and a built-in encoder, positioned between the fan and motor casing. This means users are able to carry out motor-speed and position control applications, without any significant increase in the size of the motor.
