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
- torque close to the nominal one at 0 rpm (only in a closed loop vector system)
- 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)
