SMB Servo Motors
Font Size A A A

The SMB/SME/SMH Series of highly-dynamic brushless servo motors have been designed to combine the cutting-edge technology of Parker Hannifin products with an extremely high performance. Thanks to the innovative “salient pole” technology, the motor’s dimensions are considerably reduced with significant advantages in terms of specific torque, overall dimensions and dynamic performance. Compared to traditional technology brushless servo motors, the specific torque is approximately 30 % higher, overall dimensions are considerably reduced and, consequently rotor inertias are extremely low. Thanks to the high quality Neodymium-Iron-Boron magnets, and also the encapsulation method used to fasten them to the shaft, these industrial servo motors can achieve very high acceleration and withstand high overloads without risk of demagnetisation or detachement of the magnets. Specific applications for the SME Series include all types of automation systems, especially those for the packaging and handling industry, and all those applications where very high dynamic performances and very low inertias are required. Winding options suitable for operation from both 230VAC and 400VAC are available, with a maximum nominal speed rating of 7500 min-1 (depending on frame size and feedback device), as well as holding brake and IP65 rated versions. The SME and SMH versions have encoder feedback options which include incremental, single-/multi-turn SinCos absolute types, plus the SME also offers the single cable Hiperface DSL system.
