3.3 POWER ENTRY MODULE (PEM)
The present Power Entry Module (PEM) consists in a single unit includings switch, fuses, suppresses noise and power
supply inlet.
3.4 IBP BOARD
The wheel balancer is equipped with integrated power supply and controller
board.
The PCB board software loading or updating is done with a MMC/SD card.
The replacement of the board always requires the software loading,
balancer set up and calibration of the machine and it is mandatory to load
the software with all connetcors plugged to the PCB board.
3.5 CAPACITORS
The balancer is equipped by two capacitors. they are of 10 and 20 uF
capacitors. The function of both is to start up of the motor
3.6 V.P.M. VIBRATORY ASSEMBLY
This balancer is equipped with a V.P.M., Virtual Plane Measurement, Vibratory Assembly technology. Instead of using
force measurement at widely apart positions, a compact set up is constructed . It is composed as following:
- The main shaft
- Two transducers
- The optoencoder unit
- The power clamp optoencoder (power clamp version only)
- The motor
The vibratory assembly is the central module of all wheel balancers.
It consists of the force guidance structure for directing the alternating unbalance forces via the transducers. The main
shaft is supported on ball bearings in the vibratory tube with the wheel adaptor at the right-hand end. The drive system
is then propelling and stopping the main shaft.
The incremental encoder B8 is acquiring rotational travels, direction of rotation and absolute angular position of the
main shaft.
The vibratory assembly is fastened and supported towards the ground by the cabinet, so that unbalance produces a
