The “R” Series is made up of a new generation of asynchronous standard motors (SMR) or brake motors (BAR or BMR), 4 and 6 poles and IEC frame sizes from 56 up to 132. Available nominal torques range is from 0.4Nm to 37Nm on 4 pole motors while it’s from 3.88Nm to 54.71Nm on 6 pole motors. R series motor is designed to be controlled by inverter only. The reference frequency at a voltage of 400V is 120Hz instead of 400V 50Hz. The special technology allows to the R series motors to have the following features: • constant torque from 3 to 120Hz • higher Power Density (same power in smaller motor sizes) • reduced moment of inertia compared to a motor with same power (high dynamics) • faster acceleration and deceleration times • excellent behaviour during transients (4 poles) and in continuous duty (6 poles) • optimized for use with different types of inverters in the market • balancing suited for operation with high acceleration • standard motor sizes and mounting • low noise • standard electrical wiring • encoder option available • user friendly product (connectors not needed) On standard, R series motors are equipped with thermal protectors, rotor and stator magnetic steel with advanced magnetic properties, motor winding specifically designed and impregnated for operation at high frequency, higher grade rotor balancing and bearings resistant to high rotation speed. All the options of standard motors series are also available for the R Series IP54 enclosure rating is factory standard for brake motors while IP55 for standard motors.
