Electric Screwdrivers AIR NUTRUNNER MOTORS

Detailed Description

Fiam air nutrunner motors are designed for use in single or multi-spindle (see photo 1) in manual or automatic fastening units, or in machines such as rotary tables in automatic assembly lines (see photo 2). fiam nutrunner motors are designed and manufactured for continuous and heavy duty applications by providing extremely accurate torque tightening systems. the fastening units using fiam air motors can be designed and built by the customer or, as is more generally the case, by fiam.

Series features

• Starting system
  - Air nutrunner motors can be automatically push started, or started by direct remote control. Automatic push starting is a simple and economical system for only right hand rotation motors. The motor starts automatically when a push of about 2 or 3 Kg is applied directly to it. This is the recommended system for starting motors installed on automatic fastening slides. Direct starting from a remote control signal is achieved by the application of a 3-way pneumatic control valve (on right hand rotation motors), or 5-way control valve (on reversible motors). Direct starting is recommended for multi-spindle assembly systems where the operator's effort has to be reduced.
• Cycle control
  - The use of nutrunner motors with clutches enables control of the screw tightening cycle by a pneumatic signal generated by the motor itself. With suitable processing and connections, this signal can be used to trigger visual or acoustic indicators (lights or buzzers) to warn the operator of the end of each cycle, torque value reached, etc. or to control the up-down movement of ancillary equipment or other cycle sequences. The pneumatic signal is available from a special hole in the motor casing.
  Fiam Research & Development Service is equipped with a testing bench for air nutrunner motors which makes it possible to run very careful trials. In fact, these products are used on high-yield automatic machines and must guarantee top performance and reliability. This new instrument of modern conception monitors motor functions during the whole fastening cycle as well as elaborating in real time, by means of a computer, the data relative to the pneumatic pressure signal in each of these cycles. This guarantees great working safety for air nutrunner motors and thus giving excellent performances on whatever assembly equipment they are used.
