5. Mechanical Mounting
5.1. Preparations
•
Attention! Observe the safety instructions in chapter 4.
• Make sure the drive will not be operational for the time of tachogenerator
installation.
• Prior to any installation work, switch off overall voltage supply and ensure
machinery is idle..
• We recommend sufficient contact surface according to the dimensions specified in
chapter 8. For tachogenerator type identification see product label.
• Prior to installation, make sure any motor parts protruding into the tachogenerator
are clean and free from lubricants or oil. Lubricants or oil heating up may affect the
collector and cause voltage drops, worse residual ripple, lamella short-circuiting or
groove formation with severe carbon abrasion.
5.2. Installation
• Make sure the necessary preparations for installation according to
chapter 5.1. are present.
1. Slide rotor onto drive shaft.
Important: Rotor must smoothly slide along drive shaft, do not apply force.
Never use a hammer. Where fit is tight, use a tool supported by the steel hollow
shaft in order to prevent the rotor from getting jammed.
2. Observe dimension „b“ . See dimensional drawings in chapter 8. (b = 17+1).
3. Secure tachogenerator onto drive shaft using the screws according to drawing (see
dimensional drawing). Observe the tightening torques of the mounting screws.
