The brake application time specified in the technical data for the brake, which is t2l for cut-off in the AC circuit, applies only when the supply is separate. This should align the position of the brake caliper with the rotor. A decrease in braking torque. The spline will have the best initial backlash tolerance--typically under two degrees. Tilts from full vertical to . It is typically activated by depressing the brake pedal and pulling up the EPB button and deactivated by pressing a button with just a fingertip. Introduction Permanent magnet tension control brakes are primarily used for either overload protection as a torque limiter or to control tension of a material. Most manufactures publish torque curves showing the relationship between dynamic and static torque for a given series of brake. With this unique system developed by INTORQ . With a fixed armature design a brake will eventually simply cease to engage. Regardless of the transmission youre driving (automatic or manual), whether you want to park on a slope or level parking lot, or whether the weather is inclement or unpleasant, you should always park with the emergency brake. Electric Motor Brakes - KEB servo motor brake). In the maximum torque condition, discs are rotated until the fields are directly opposing each other, so the magnetic fields bump against each other and have to travel circumferentially through the disc putting the maximum amount of magnetic drag on the disc. The friction material is flush with the surface of the brake because you want to have metal to metal contact between the coil shell and the armature. Larger units can have adjustable torque settings that can be changed by an end user. coupling, etc.) This happens relatively quickly typically (.2 -2 sec).
