SMH Series

Low-Inertia Brushless Servo Motors for Compax3 & PSD1 Servo Drives

Available in 60-170mm frame sizes, SMH motors use innovative salient pole technology to achieve low rotor inertias and high dynamic performance. SMH motors have the option of either Resolver or Encoder Feedback.

The SMH series brushless servo motors have been designed to combine cutting-edge technology with extremely high performance.

Utilising innovative ‘Salient Pole' technology, featuring Neodymium-Iron-Boron magnets uniquely encapsulated to the motor shaft, SMH synchronous servo motors can achieve very high accelerations and withstand high overloads without any risk of demagnetisation or detachment of the magnets. Additionally the motor's dimensions are considerably reduced, offering significant advantages in terms of specific torque and dynamic performance. Compared to traditional-technology brushless servo motors, the specific torque of SMH serrvo motors is approximately 30% higher and rotor inertias are extremely low, making it especially suited to highly dynamic applications.

The SMH brushless servo motor series offers a high degree of flexibility thanks to its extensive range of motor frame configurations, flange and shaft options, feedback devices and winding options.
