Measuring angles with rotary encoders

In Heidenhain rotary encoder with stator coupling and integral bearing, the graduated encoder disk is coupled straight to the shaft to be measured. The ball bearing is used to guide the scanning unit on the shaft, supported by stator coupling. Stator coupling should soak up only the torque occurring because of friction in the bearing while angular acceleration of the shaft happens, therefore it minimizes both dynamic and static measuring error. Axial motion of the measured shaft is compensated by coupling mounted on the stator. Few more advantages of stator coupling are:
• Very Simple mounting
• High natural rate of recurrence of coupling
• Short length
• Hollow through shaft possible

Measuring angles with angle encoders

Angle encoders of Heidenhain are featured by very high accuracy and precision values in the arc second range

Few Examples for application are :
• spin head on machine tools
• Rotary table on machine tools
• Printing unit
• C axes on lathes works better with angel encoder
• Gear testing machines
• Angel encoder can be used for Telescopes
• Spectrometers

There are three different principles of mechanical design:
• Angle encoders with integrated stator coupling
• Angle encoders with integral bearing
• Angle encoders with hollow shaft and

stator coupling is designed that it should only absorb that torque occurred by friction in the bearing while angular acceleration of shaft. So for outstanding dynamic performance there are RCN, RON, RPN angle encoders and absolute encoders.

With an incorporated stator coupling, the system accuracy and precision also includes the deviations from the shaft coupling.

More advantages are:
• C axes on lathes
• Compact size for limited installation space
• Hollow shaft diameters up to 100 mm for leading power cables
• Simple mounting

Angle encoder with integral bearing
ROD angle encoders with solid shaft are mainly suited for applications where superior shaft speeds and better mounting tolerances are necessary. The shaft couplings permit axial tolerances of ± 1 mm.

Angle encoder without integral bearing
Modular angle encoders such as ERA and ERO angle encoders with no integral bearing are for integration in apparatuses and machine elements. They are suitable for the following requirements:
• Segment solutions
• High shaft speeds up to 40000 rpm
• big hollow shaft diameter upto 10 m with a scale tape

Modular magnetic encoders

The tough ERM modular magnetic encoders are particularly suitable for use in manufacture machines. Their huge accessible inside diameters, their tiny dimensions and the small design destine them for
• spindle direction on milling machines
• the C axis of lathes or auxiliary axes
• rotary and tilting


C axis on lathes
The ERMs has been the ideal encoders for C axes on lathes. They have huge internal diameter to allow bar material to be machined without any boundaries and they have high resistance to contamination. It reduces the position errors for better accuracy and precision.

Rotary and tilting tables
Tilting axes and Rotary tables need encoders with very high signal excellence for position and speed control. RCN series Encoders with optical measuring standards, accomplish these necessities in a perfect way. For average accuracy necessities magnetic modular encoders can also be used. Because of their tiny signal period of 200 µm, the ERM 2200 encoders feature mainly low position error within one signal period and hence permit comparatively high axis speed constancy. The typical benefits of magnetic modular encoders, such as tolerance to contamination and huge internal diameters are very supportive in this application.

Spindles on milling machines
Spindles are among the important components of machine tools and considerably influence their function. The spindle features are determined by bearing systems, design, drives but also the encoders make a critical involvement in performance. Speed of over 40000 rpm is no problem for the ERM 2900. The ERM 2400 encoders with 400 µm signal period has better accurateness and precision.
