1 Electromagnetic Brake Motors This power off, electromagnetic brake coupled to reversible motors and induction motors (three-phase type) provides output of W W (three-phase: W W). These motors are best suited for applications in which loads must be held. Features These motors incorporate C electromagnetic brakes which are activated when the power is shut off. When the power supply is turned off the motor stops and holds the load. Holding brake force is. oz-in ( mn m). oz-in ( mn m). These units are excellent as emergency safety brakes.

Low Voltage Directive The figure above indicates an example of the structure of the electromagnetic brake motor. The electromagnetic brake operates on the basis of a spring which presses the armature against the brake hub, stopping the motor and holding the load. When the electromagnetic brake is excited, it attracts the armature and the brake lining is pulled away from the brake hub. The motor is able to turn freely.

Using the connection shown in figure w, however, results in a msec. increase in braking time over that shown in figure q, with a corresponding increase in overrun. The reason for this is that the electromagnetic energy of the motor continues to have an effect on the coil of the electromagnetic brake, so that the electromagnet continues to operate for msec. even though the excitation has been canceled. The brake therefore takes longer to engage. q Normal Connection Line SW SW R R R R C C C ON C C C White Red Black Motor Orange Electromagnetic Orange brake w Simplified Connection Line SW SW R R R C C ON C C C White Red Black Motor Orange Electromagnetic Orange brake - ORIENTL MOTOR GENERL CTLOG -

7 Starting and Braking Characteristics s an example, we have calculated the motor starting time, braking time and overrun when driving an inertial load (J L = 7 oz-in ) for the motor RKGN-MUL when combined with the gearhead GNK. The overrun of the motor shaft based on the graph on the next page is: NM. revolutions of gearhead output shaft is: N G NM.. revolutions ( ) i J L Gearhead Motor GNK RKGN-MUL First, convert load inertia to its corresponding value at the motor shaft. JM JL 7. [oz-in ] i J L : Inertia of the load [oz-in ] J M : Inertia at motor shaft [oz-in ] i : Gear ratio Starting time and braking time Using the graph again gives: Starting time t msec Braking time t msec The starting time of an electromagnetic brake motor is equal to the motor starting time plus the electromagnetic brake release time. If the electromagnetic brake is left released, the motor can be started much faster. Optimum time for release of the brake is at least msec. before starting up the motor.
