No one would come up with the idea in the car at full speed the handbrake on. To delay the car specifically, the driver uses the brake pedal. Even with equipment- and machine applications with dynamic braking a dose, even lag is often desirable. With the new intelligent braking torque control module of Mayr Antriebstechnik can be delayed until evenly and gently equipment and machinery. The module is suitable for use in smart, networked machine.

Since spring-applied brakes, unlike car brakes, by design only know the two operating states "brake torque present" and "brake torque canceled", each braking operation takes place with the maximum available braking torque. The drive specialist offers with the intelligent braking torque control module an economically attractive solution toRoba-stop "spring-applied brakes To generate a variable braking torque and thus to delay machines smoothly and gently.

For devices with changing load such as industrial trucks, the brake is so far dimensioned based on the maximum load. However, it does not always make sense to work with the full braking torque. Thus, with partial loading a greater delay can lead to damage to the cargo or even to slippage of the wheels. If the system detects the operating conditions and converts this into a default signal for the switching device, an electronic braking torque control is possible. With the system, the contact pressure on the brake pads and thus the braking torque during operation can be varied steplessly. In addition, in applications that require a constant braking torque in tight tolerance limits, compensate with the braking torque control negative influences on the brake torque constancy.

The intelligent switching device is operated with 24 or 48 V DC voltage and can control brakes with a coil rated current of 10 A or 5 A. Via two digital inputs, the resulting clamping force for the brake rotor can be set to 25, 50 or 75% of the rated spring force. Alternatively, a stepless analogue default signal from 0 to 10 V is possible. Sensorless, the switching device determines whether the armature disk has been tightened or dropped. This can be used to automatically adjust the overexcitation time. The fact that the intelligent switching device detects the switching state of the brake, no usual microswitches or proximity switches are necessary. The device also closes for possible wear reserve and detects if necessary inadmissible heating.
