First, use
The Series Electromagnetic Power for power electromagnetic pull, power-off friction brake brake. And Y series motor supporting generate a new type of YEJ series electromagnetic brake three-phase asynchronous motor. Widely used in metallurgy, construction, chemical, food, machine tools, packaging machinery, fast parking and accurate positioning can be used in a power outage (anti-insurance) braking and other occasions.
Second, the characteristics
This brake has a compact structure, easy installation, wide applicability, low noise, high operating frequency, sensitive, reliable braking, etc., is an ideal industrial modernization and implementation of automation components.
Third, the working principle and the installation and maintenance
Electromagnetic Power by the excitation part (yoke coil 2, the spring 3, the armature 4), brake discs, splines nine sets of main component parts. Excitation part of the 7 installation by mounting screws on the base, the rotary joint mounting screws to adjust the air gap to the specified value δ, the reverse rotation out of the hollow bolt 6, the top tight excitation part. Spline sets 9 through the key with the drive shaft is connected; brake disc spline engagement with the spline sleeve 9. When the coil power outage in the spring 3 under the action of the brake disc 8 and the armature 4, the base end 10 (or brake plate 11) to produce friction, the axis brake to the drive shaft through the splined sleeve 9 . When the coil 2 is energized, the electromagnetic force, the armature 4 being sucked to the yoke, so that the brake disc 8 loosen drive shaft brake to lift. (Equipment maintenance power outage by the axial pulling the manual release mechanism, the brake release.)
Should be installed before the friction surface oil, debris clean.

V. Notes
A friction plate are wearing parts. After wear, the air gap increases when the maximum permissible air gap of more than brakes should be readjusted, or affect the normal work, or even damage the brake and motor.
2, when the frequent operation, the brake should be checked regularly whether or loose fasteners, if loose, should be re-adjusted to tighten before using.
3, when the brake is mounted on the motor, motor starter difficulties or noise, you should check the brake, this manual adjustment.
Six, the control circuit
The brake coil operating voltage of conventional DC 99V and 170V. The factory has designed for brake supporting ZL, ZL1 rectifier power supply, input and output protection circuit, small, reliable, the overall seal can be installed directly at the motor terminal box, see wiring the ZL rectifier power supply wiring diagram.
