These electromagnets have the most widely
used ‘U’ shaped soft iron yoke. The soft iron
is of a special quality, structurally uniform, well machined
and finished to meet the rigid standards.
The pole pieces are made from dead annealed
soft iron blocks of the best quality available. They are well
shaped, machined and finished. The air-gap is continuously
variable with two way knobbed wheel screw adjusting system.
EMU-50V is supplied with flat pole pieces and EMU-50T is supplied
with tappered pole pieces.
The coils are wound on non-magnetic formers
with uniform layers of S.E. copper wire. The new and modern
design of the coils provides good thermal conductivity characteristics
and eliminates troublesome hot spots even at high magnetic
DPS-50 is an inexpensive and high performance
constant current source suitable for small and medium sized
electromagnets. Although the equipment is designed for the
Electromagnet, Model: EMU-50, it can be used satisfactorily
with any other electromagnet provided the coil resistance
does not exceed 6?.
The current regulation circuit is IC controlled
and hence results in the highest quality of performance. Matched
power transistors are used to share the load current. The
supply is protected against overload, short circuit and transient
caused by the inductive load of the magnet.
