Grid Plate Braking Resistors — Punched in Brisbane

Grid plate braking resistors dissipate electrical energy as heat during motor deceleration in cranes, conveyors, ship loaders and other heavy-duty equipment. For Australian ports, mining operations and bulk material handling facilities, resistor selection needs to account for repeated braking cycles, vibration, dust, heat and coastal exposure.

Backer Cynebar Ohmic designs and manufactures custom grid plate resistors in Brisbane, Australia, for dynamic braking, motor control and industrial power applications. Our engineering team tailors resistor assemblies to the electrical ratings, duty cycle, installation space and environmental requirements of each project.

Grid Plates Punched in Brisbane. Built for Heavy-Duty Braking.

Grid plate resistors combine rugged construction, energy absorption and heat dissipation for demanding braking applications. Heavy-duty alloy plates accommodate vibration, mechanical shock and frequent start-stop cycles, while open-grid construction allows airflow around the elements. Suitability depends on the electrical requirements, operating duty and environment.

Custom enclosures can be designed for site conditions such as mining dust, salt-laden coastal air and high ambient temperatures like 50°C.

Rotor Resistance Starters for Iron Ore Mining Conveyors

For conveyors driven by wound rotor (slip ring) induction motors, grid plate resistor banks can form part of a rotor resistance starter. Resistance is progressively switched out as the motor accelerates. This starting function is distinct from dynamic braking. Backer Cynebar Ohmic selects resistor values, starting stages and thermal capacity to suit the motor, conveyor load and starting duty.

In-House Grid Plate Resistor Testing in Brisbane

Backer Cynebar Ohmic’s in-house grid plate resistor testing facilities in Brisbane offer testing at currents up to 1,800 A to support design verification under agreed test conditions. Discuss your application with our engineering team to confirm the applicable current, test duration and acceptance criteria. The scope of verification depends on those agreed conditions.
