Industrial Gearboxes

Electric Motor Brake is a spring-set fail-safe multiple disc brake designed for high torque in a compact envelope. The brake uses radially-spaced coil springs to keep the friction discs compressed against the armature when the coil is not energized — this is the "fail-safe" behavior that holds the load when power is removed. When the DC coil is energized, electromagnetic force overrides spring pressure and releases the friction discs for drag-free shaft rotation. Standard coil voltages are 24V, 48V, 90V and 190V DC. The brake ships ready for installation by sliding over the keyed motor shaft and bolting to a frame member. Optional C-face non-magnetic flanges allow direct mounting on C-frame motors without an adapter. Custom coil voltages, mounting flanges and disc stacks are available for OEM applications. Suitable for machine tool spindles, conveyors, hoists, packaging equipment and any application that requires positive holding when power is removed.

What is a single-phase motor? A single-phase motor is an electrically-powered rotary machine that can turn electric energy into mechanical energy.

We use the single-phase power system more widely than three phase system for domestic purposes, commercial purposes and some extent in industrial uses.

An induction motor or 3 phase induction motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding

Three-phase motors are more efficient than single phase motors and are commonly found in applications requiring more than 7.5 horsepower. Although the National Electric Code does not specify specific conductor colors for three-phase current, it is common to use black, red and blue wires to identify lines L1, L2 and L3 respectively.

The polyphase induction motor invented by Nikola Tesla in 1886 had been developed by 1895 virtually into its present squirrel-cage form. The slip-ring induction motor was developed a short time later.
