Brushless Servomotor

Parker Hannifin has introduced a new model to its SMB Series brushless servo motor range. The SMB170 not only extends the torque capability of the series to 60Nm, but also offers a high degree of flexibility to food processing, packaging, material forming and handling machinery OEMs thanks to an extensive range of motor frame configurations and options. Utilising innovative 'Salient Pole' technology featuring Neodymium-Iron-Boron magnets encapsulated to the motor shaft, the motors can achieve high acceleration and withstand high overloads without any risk of demagnetisation or detachment of the magnets. Compared to traditional-technology brushless servo motors, the specific torque is approximately 30% higher and rotor inertias are low making it especially suited to highly dynamic applications. The addition of the motor means the series is now available in sizes from 60 mm to 170 mm, nominal torque range from 0.35 to 60 Nm and nominal speeds up to 7500 rpm. The product is available in two lengths (306 mm / 409 mm) which are rated at 35 Nm and 60 Nm respectively. Both are equipped with a front holding brake that provides better performance and improves thermal dissipation.
