DRC Electronic Motor for Worldwide Use

Sew-Eurodrive has announced a new permanent magnet synchronous electronic motor to complement its range of mechatronic drive systems. The DRC electronic motor can be directly coupled with SEW’s comprehensive gear unit range, making it highly flexible. It is also suitable for worldwide use, with its efficiency surpassing the highest efficiency IE4 Super Premium Efficiency class.

The DRC electronic motor series consists of a permanent-field synchronous motor and matching integrated drive electronics. The motor is also available as brake-motor deeming it suitable for hoists and inclined conveyors. A highly efficient bevel, helical or parallel-shaft gear unit can be mounted directly via the flange and output shaft. Together with a gear unit from SEW’s modular range, manufacturers can get a versatile and flexible mechatronic drive system. This combines the three core competencies of Sew-Eurodrive in one drive solution: gear unit, motor and drive electronics. The integration and coordination of all three drive components leads to a long and reliable service life, and so ensures high system performance. The motor efficiency of the DRC surpasses the requirements of the highest efficiency class IE4 (Super Premium Efficiency), making it possible to save up to 50% of the energy costs compared to conventional electric drive technology.

The DRC electronic motor is setting standards for functionality and efficiency. For example, the unique Single Network Installation (SNI) technology from Sew-Eurodrive requires only one 4-wire cable for power supply and communication. This reduces the amount of cabling efforts significantly; up to 60% of installation costs can be saved. For stand-alone applications or systems with simple drive functionalities, variants with binary control and AS-Interface communication are available. The fourth variant is equipped with the CAN-based SEW system bus SBus, which provides excellent flexibility for integrating various fieldbus networks, increasing system performance for the realisation of sophisticated drive tasks.

The DRC electronic motor series is available in two distinct frame sizes covering a power range up to 1.5 kW with a further 250% overload capacity. Available with an IEC flange option and a degree of protection up to IP66, the DRC motor can be used for stand-alone motor application in challenging environments. System emergency stop functionality can be easily realised in conjunction with the integrated Safe Torque off Safe Circuit- SIL3 according to IEC 61800-5-2:2007.

The DRC electronic motor covers a wide voltage range from 380 to 500 V at 50/60 hz and meets all application standards, directives and efficiency regulations. This greatly reduces the number of available variants and simplifies selection and project planning, as the same drive type can be used all over the world without any problems.
