The requirement to have an effective and reliable safety braking system within a driven mechanism is becoming prerequisite, especially when there is a risk to the machine operator. ABSSAC is now supplying an excellent range of electromagnetic brakes from Miki Pulley of Japan. The high-quality safety brakes are actuated as soon as the holding electrical current is severed. Watch the short video below to find out more.
Within the safety brake there are optimised springs that are held in a compressive sate by an electromagnet; as soon as the power is removed from the electromagnet, the springs apply the braking force. The designs provide excellent performance in emergency braking and can also be used effectively to hold stop positions for long periods of time without consuming power. The range delivers quiet braking, a long service life and high torque capacity from compact designs.
Operational costs can also be lowered by using the BXR-LE series. With all safety brakes, when a machine is running, the brake is continuously drawing electrical current in order to maintain the brake in a released condition. However, the necessary electrical energy consumed when the brake starts to release differs greatly from the current draw requirement when the brake is held in the released condition. By optimising this differential with an over-excitation power supply, the operational energy saving can up to 90 per cent.
Typical applications for the BXR-LE brake include integration within servo motors and robotics where the space-saving benefits are maximised.
