The 700 Series caliper is a
magnetically engaged caliper consisting of two (2) independent and
fully floating caliper halves, mounted on common supporting pins
upon which they slide axially or at 90 degrees to the rotor face.
1)
The 700 Series employs a truncated horseshoe electromagnet
as its main caliper body; each leg of the horseshoe is encircled by
an electric coil. The two (2) coils are wired in series as they act
on a common iron path or circuit.
2) The 700 Series friction
shoe is composed of both iron and fiberglass frictional components
arranged in a manner that allows the shoe to become part of the
magnetic circuit.
3)
The magnetic field is generated in the truncated horseshoe
electromagnet, passes through the specially designed shoe, and into
the disc rotor. This allows a continuous magnetic circuit to be
formed and a very serious force being developed between the shoe and
the disc rotor.
4)
Since the horseshoe main frame and the shoe are retained
in a mounting frame and unable to move, when the field is energized
the shoe captivates the disc rotor with amazing force depending only
upon the voltage applied to the coils.
5)
Since the coils are inductive and resistive devices with
the resistance being a fixed value; if you vary the voltage the
amperage will also vary.
6)
Electromotive field strengths are dependent on only two
(2) things i.e., the number of windings in the coil and the amount
of amperage running through the coil.
7)
Therefore E=IR or Voltage equals Amperage times
Resistance.
►If you increase the voltage you will
increase the amperage.
►If you increase the amperage you will
increase the electromotive field strength.
►If you increase the electromotive field
strength you increase the brake torque — and they are in direct
proportion to one another.
8)
The 700 Series was designed to replace the hydraulic
bridge brake on overhead cranes in the hot metals industry.
9)
