Mechanical engineering often faces the task of converting rotational movements into powerful linear movements. The associated development costs can now be cut dramatically by using modular spindle drives in maxon motor’s modular system.
The GP 22 S and GP 32 S gearheads, specifically adjusted for spindles, are designed to withstand high loads, and the special spindle intake means that customer-specific spindles can be assembled with ease in significantly less time.
There are three different standard spindle types to choose from: metric spindles, trapeze spindles and spherical rotating spindles. The spindles are available in steel or ceramic variations up to 200 mm in length and supplied with matching Spindle nuts.
Gearheads, motors, encoders and controllers from maxon’s standard program are used to drive the spindles. The individual components of the spindle drives are all compatible to help create highly effective drive solutions. These modified planetary gearheads are available in two different sizes, with diameters of 22 mm and 32 mm. Reduction ratios of 3.7:1 to 1093:1 provide maximum torques up to 6 Nm and speeds of up to 1600 min-1. The additional axial bearings of these gearheads can also withstand powerful axial forces from the spindles.
Depending on the application, maxon’s DC brushed or brushless motors may be used to drive the system. Motors may be fitted with compatible encoders which is critical for accurate positioning. The EPOS positioning controller is recommended to control the motor-encoder combination. It can also directly evaluate end-switches and other sensors. If a standalone system is desired, the programmable EPOS P variation may be used.
