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.
