ADVANTAGES AND DISADVANTAGES OF
SYNCHRONOUS RELUCTANCE
MOTOR
Advantages
v There is
no concern with demagnetization; hence synchronous reluctance machines are
inherently more reliable than PM machines.
v There
need not be any exciting field as torque is zero, thus eliminating
electromagnetic spinning losses.
v Synchronous
reluctance machine rotors can be constructed entirely from high strength, low
cost materials.
Disadvantages
v High cost
than induction Motor.
v Need
Speed synchronization to invertor output frequency by using rotor position
sensor and sensor less control.
v Compared
to induction motor it is slightly heavier and has low power factor.
v By
increasing the saliency ratio Lds/Lqs, the power factor
can be improved.
APPLICATIONS OF SYNCHRONIZATION
v Metering
Pumps.
v Auxiliary
time Mechanism.
v Wrapping
and folding Machines.
v Proportioning
Devices on Pumps or conveyors.
v Synthetic
fibre manufacturing equipment.
v Processing
continuous sheet or film material.
