Flexible, ultra-compact 40mm frame servo motor

Parker Hannifin has introduced a 40mm size to its highly-dynamic and compact SMH/SMB Series brushless servo motor range. The 40mm variant not only extends the torque capability in its smallest size starting from 0.19Nm, but also offers a degree of flexibility to food processing, packaging, robot and handling machinery OEMs due to a range of motor frame configurations and options.

The motor’s dimensions have been reduced to offer advantages in terms of torque and dynamic performance. When compared to traditional-technology brushless servo motors the specific torque is approximately 30% higher and rotor inertias are low, suiting it to dynamic applications.

With the addition of the SMH40/SMB40 the SMB series of servo motors is now available in sizes from 40 to 170mm, offers nominal torque ranges from 0.19 to 60Nm and features speeds up to 7500rpm.SMH40/SMB40 is available in two lengths, 92/109mm, which are rated at 0.19 and 0.38Nm respectively, 230Vac.

SMH40/SMB40 features the same feedback types and options as the rest of the SMH/SMB range, including a robust resolver interface to multiple high precision digital position feedback options. The product can also be ordered as a single cable servo motor featuring the HIPERFACE DSL feedback system - a completely digital and interference-free absolute position feedback system for servo motors and drives. This integrates the encoder communication into the motor power connection cable eliminating the need for a separate feedback connection cable between drive and motor.
