    Package benefits

    High output synchronous reluctance motor and drive packages offer performance comparable with permanent magnet motors. The synchronous reluctance motors combine conventional, proven stator technology with an innovative rotor design. The industrial drive is loaded with purpose-designed software, and the package as a whole is optimized for pump and fan applications.

    Cool motor cuts the cost of runningThe synchronous reluctance rotor has neither magnets nor windings. Rotor losses are virtually eliminated, resulting in very cool running. This advantage is the basis for a design that delivers high power density coupled with high efficiency. Other benefits include high output, a very compact size, and low energy consumption, especially in variable speed operation with partial loads.

    Traditional induction motor Losses High output SynRM motorTraditional induction motor

    Superior reliability minimizes the cost of downtimeBearing failure causes approximately 70 % of unplanned motor outages. Bearing temperature in the synchronous reluctance motor are low, which extends bearing lifetime and service intervals for lower maintenance costs and improved reliability. Even when a bearing eventually needs replacing, there are no magnetic forces involved unlike in a permanent magnet motor so changing bearing is as fast and easy as with an induction motor.

    Motor and drive highlights

    Motor highlights Powerful yet highly compact to two frame sizes smaller

    than a conventional motor. Can be customized like an induction motor: variant codes

    and mechanical construction are based on the proven M3BP cast iron Process performance motors. The same easily available and replaceable parts are used.

    Straightforward design without magnets or rotor cage. Competitive when compared to both traditional and other

    new technologies. Higher reliability through lower bearing temperatures. Higher efficiency than in conventional VSD-driven induction

    motors.

    ACS850 drive highlights Modular structure with a wide range of options means that

    users need purchase only the features they require. Can run induction, permanent magnet and synchronous

    reluctance motors, so can therefore be deployed on other motors if needed.

    Compact and convinient memory module stores drive settings and can be installed in a new drive by anyone on the site.

    Slim design means the drive occupies the minimum cabinet space.

    Drive setup simply involves entering the parameters from the motor rating plate just as with an induction motor. No encoders, position sensors or other feedback devices are needed.

    Same power smaller motorThe High output synchronous reluctance motor is up to two frame sizes smaller than an induction motor with the same output. The size advantage increases with speed so the benefit is greater for 3000 rpm than for 1500 rpm applications. A light, compact motor results in cost-efficient installations.

    Same size higher powerThe size advantage of synchronous reluctance motors can also be exploited to increase capacity without changes in the motor installation. In other words, a high output synchronous reluctance motor can deliver up to twice the output of an induction motor of the same size. Again, this power advantage is greater at higher speeds.

    IE3 compact design without compromising efficiencyHigh output synchronous reluctance motors in sizes 160 - 315 meet or exceed the efficiency levels of IE3 induction motors when both types of motor are VSD-driven. The technical data section of this catalog shows motor efficiency values with a VSD supply. The efficiency values and IE class of induction motors are usually determined with a sinusoidal supply.

    Additional losses attributable to the VSD supply are typically 10 - 30 %, which means that about one IE class is lost in motor efficiency when compared with a sinusoidal supply. This must be noted when comparing the efficiency values of different motor types. It should also be noted that the energy savings gained by speed control are much greater than the loss in motor efficiency.

    Why are the motors packaged with drives New technology motors are more challenging from the control point of view than traditional induction motor and drive packages. When selecting a new technology motor and drive package, it is important to ensure that the package is suitable for the application the drive must have the right control software for the specific application. Contact ABB for information concerning available products and supported applications. The performance of synchronous reluctance motor is verified with ABB drives. Performance and functionality with other drives can not be guaranteed.

    Package selection The technical data section lists matched motor and drive packages for easy selection. The packages deliver the rated power at any speed between nominal and maximum. Refer

    to ABB for package selection at other speeds, or use the DriveSize software.

    Insulation protection Synchronous reluctance motors have the same stator winding insulation as other ABB low voltage motors. The insulation is approved for a 500 V VSD supply. For voltages above 500 V, follow ABBs instructions regarding the correct insulation system and the output filters drive.

    Bearing currents Synchronous reluctance motors rated above 100 kW are equipped with one insulated bearing as standard, which together with the correct cabling is sufficient to secure trouble-free operation up to 350 kW. Above 350 kW the drive should be equipped with a common-mode filter as an additional measure.

    Cabling, grounding, and EMCSynchronous reluctance motors are not equipped with EMC filters as standard. The variant code to order EMC cable glands is +704.

    The use of a frequency converter sets higher demands on the cabling and grounding of the drive system. In other than exceptional circumstances, the motor must be cabled with shielded symmetrical cables and cable glands providing 360-degree bonding (EMC glands). For motors up to 30 kW, asymmetrical cables can be used, but shielded cables are always recommended, especially if there are sensitive components in the driven application.

    For motors from frame size 280 upwards, additional potential equalization is needed between the motor frame and machinery, unless the motor and the driven machine are installed on a common steel base. When a steel base is used for potential equalization, the high frequency conductivity of the connection must be checked. For more information, see the ABB manual Grounding and cabling of the drive system, 3AFY61201998 R0125 REV B.

    To meet EMC requirements, special EMC cables must be used in addition to the correct cable gland mounting, with additional special earthling pieces. For more information, refer to drive manuals.
