High starting torque

Robust in construction

Having lighter gauge winding

No brushes and commutation

Requires less space

Installation and running cost is less

Fast response and wide speed range of control

Power circuit and control circuits are simple

Hoists

Elevators

Conveyors

Centrifugal pumps

Produces required firing current to the firing circuit

Provides variable voltage to the field winding of motor

Provides a constant voltage to the field winding of motor

Provides a constant voltage to the armature of the motor

Not suitable for high speed operation

More complex with a single power conversion

More expensive than AC drive for high capacity motor

Installation of DC drives is more complicated
