WebCaliper disc brakes are normally spring-set and released by AC thrusters. Single caliper disc brakes apply substantial shaft and motor or gearbox loads that require careful analysis to ensure safety. Thruster brakes (either shoe or caliper disc) give a smooth application of the brake by means of a torque spring. WebOct 3, 2024 · To brake smoothly, a resistor is often placed in series with each stator phase when switching to countercurrent. This reduces the torque and current, as in stator starting. The drawbacks of countercurrent braking in squirrel cage motors are so great that this system is only used for some purposes with low-powered motors. 1.2 Slip ring motor gummy worm dirt cake recipe
