Miki Pulley Brakes help AGVs operate more efficiently
Miki Pulley has introduced its newest BXR-LE brakes that that are designed to provide Automated Guided Vehicles (AGVs) with controlled braking while using less power.
Computer controlled, wheel-based, and battery powered, AGVs are load carriers that travel along the floor of a facility without an onboard operator or driver. Their movement is directed by a combination of software and sensor-based guidance systems. As a mobile robot, AGVs follow markers or wires in the floor, or use vision or lasers for guided movement. They are most often used in industrial applications to move materials around a manufacturing facility or warehouse.
Because they are unattended and long-term operation is required, power for their uninterrupted operation is important. In addition, the AGV must have emergency braking capability, as well as have a default brake to hold position when not in motion. The BXR-LE brake is a power-off engaged brake designed to hold the AGV in place when not in use. When it then must navigate the production floor, the brake is energized, which disengages the rotor disc and allows free rotation of the AGV drive wheels. The brake uses 24 VDC (vehicle dynamic control) for a split second to overcome compression spring inertia to open the brake, then consumes a reported 7 VDC by utilizing the BEM power control module. According to the company, this saves battery power and minimizes the number of battery recharging operations needed to keep the AGV in continuous operation.
When compared to most other electric brakes, the BXR-LE design provides just one-third power consumption and heat generation in one-half the overall size thickness, reports the company.
Its specifications include:
- Maximum RPM: 6000
- Static friction torque range: 0.044 ft lb to 2.36 ft lb
- Ambient operating temperature: 14° F – 104° F
