Baldor Australia stock a large range of quality dc motors and precision dc motor controls. Baldors large DC Shunt Motors are designed for Full Thyristor Control variable speed drives, stock motors are supplied as force ventilated with Blower and Class ‘H’ Insulation. Baldor DC motor control ‘Series 20H’ line regenerative dc digital controls are precision controls for constant torque and variable speed.
DC Motors from Baldor
Typical applications for large frame DC motors include:
- Hoist and crane where motor peak capacities exceed 200% for several seconds, and ideally suited for line regenerative Dc motor drive systems
- Web tension applications requiring large amounts of power available from small frame TEBC DC motors
- Winder and rewinder applications where high reversals and high standstill torques required
- Downhill conveyors - well suited for DC's regenerating capabilities
- Dyno test stands where high overloads and peak torques have been traditional applications for DC motor drive systems.
Large DC Shunt Motors
- 4 pole ‘straight shunt wound’ design with separate field excitation on frames up to B200
- 4 pole ‘stabilised shunt wound’ design with separate field excitation on frames B225 and above
- IP23 enclosure standard
- High quality steel frame, annealed for optimum magnetic properties
- Heavy duty steel feet welded to the frame for maximum structural integrity under adverse conditions
- Large removable brush inspection covers allow easy access to the commutator and brush equipment
