Spindle drive systems offer minimal pitch deviation for maximum precision

05 August 2011

Available from EMS in the UK, Faulhaber high precision ball screws can now be integrated directly with its range of dc Micromotors, Brushless dc motors or stepper motors. The series BS22-1.5 enables precise linear movements with minimum travel variations of just 5µm over the total travel. In combination with their highly efficient ironless rotor motor technology, high-resolution encoders and integrated motion controllers, maximum precision is guaranteed.

Mechanical interface to the motors is achieved with a backlash-free coupling integrated into the ball screw. The all stainless steel construction of the series BS22-1.5 offers intermittent axial forces up to 500N and speeds up to 125mm/s with a maximum efficiency of 89%.

However this should only be considered as an entry level solution and countless modifications including screwlength, modified ball nuts or special lubricants are available on request.

They are ideal for the most demanding linear positioning tasks such as optical filters, glass-fibre technology, lens adjustment in optical systems or micro actuators for medical technology.
