The two primary reasons
for installing variable speed drives are process control, and energy
/ maintenance efficiencies. With our latest products, motor
powers up to 1MW (at 380V to 3,300V) are now readily available for
the mining industry.
Whatever the application,
operating environment or control system you require for the drive,
either as a part or as a complete scheme, BALDWIN & FRANCIS
Ltd. offer both the technology and expertise to assist your company
acheive its potential.
Benefits of Variable
Speed Drives

control of torque from zero to full speed
Continuously
equates drive speed to operating demands
Employs existing a.c. motors and mechanical systems
Increases component life cycle time
Reduction in maintenance costs
Reduced electrical network costs
Reduced energy costs
Voltage Sourced system.
