Post Glover Resistors Inc.
Post Glover has over 116 years of Power Resistor experience!
Post Glover Resistors, founded in 1892, has the industrial experience in power resistors to deliver proven solutions for your critical applications. We can design resistors to suit your application or draw from our extensive archive of products to provide you with the exact replacement resistor. We provide dynamic braking and motor/crane control resistors for stopping and motion control.
Post Glover Dynamic Braking Resistors
Being first a manufacturer of power resistors, Post Glover has a
vast array of Dynamic Braking Resistors to choose from. This allows
us to offer the best possible technical and economic solution for
your particular application. We have worked with many OEMs and built
a broad knowledge of their product specifications for dynamic brake
resistors, so when you call in requesting a part, Post Glover can
cross-reference the part number and quote the needed part.
Post Glover Crane Motor Control Resistors for Wound Rotor and 250 VDC
When overhead cranes are used in industrial facilities, crane
resistor banks are frequently used for control of hoisting and
lowering speeds, as well as positioning the crane itself. Resistors
are usually mounted in, or on top of, the bridge structure.
Many steel mills use DC motors because, in the past, DC power was
the best way to hoist heavy loads. Newer plants are increasingly
utilizing more readily available three-phase power, and wound rotor
motors are often employed.
Brake resistor control techniques — In hoisting and lowering
operations, some special considerations are involved. Hoisting is
straightforward — the load is resisting the motor, and positive
torque against gravity is required. In lowering an empty hook, it
may be necessary to drive the hook down, since gravity may be
insufficient to lower it at the desired speed.
