The advantage of brake systems wired in this way is when power is applied to the motor, the brake releases,(requiring no additional brake supply power wiring). The brake can be wired to the motor terminal block under the following conditions: a single speed motor; the motor is started and run across the line (i.e., no inverter or electronic soft start) . The connections shown on this page are for normal brake reaction time. For rapid brake reaction time, incorporate the contact as shown on the brake diagram located on the inside of the motor conduit box lid.  \nBrake Motor Connection  \nSingle Speed Dual Voltage-YY/Y Connection Diagram DT79 Example Motor Voltages:  \n230YY/460Y Volts-60 Hz  \n200YY/400Y Volts-50 Hz  \nBG or BGE Brake Rectifier  \nMotor wired for low voltage.

It cannot be used at elevated ambient temperatures or with unfavorable cooling conditions for the brake.  \nThe BGE Brake Rectifier -Standard for motor frame sizes 112M and larger, optional on frame sizes 71 to 100  \nThe BGE brake rectifier is a half-wave rectifier with over-voltage protection elements and electronic control for reducing the brake release reaction times.  \nThe brake operation is improved by the BGE rectifier in that it releases the brake initially by super-magnetization and then holds the stationary disc securely with reduced magnetization. Due to the exceedingly reduced brake release reaction time t1 the brake is released before the motor can build up torque and begin to rotate. Minimum wear with maximum service life and excellent switching ability are the outstanding features of the brake system.  \nIn the continuous released state the current losses are reduced to the necessary minimum so the thermal loading of the brake is very low.  \nThe use of the BGE Brake Rectifier is recommended if:  \n• Short brake release reaction times are required.  \n• High starting frequencies are encountered.  \n• High ambient temperature is present or the brake is required to be in the continuous released state while the motor is at rest or operating at low speeds.  \nThe BSG Brake Control Unit -Standard for motor frame sizes 112M and larger, optional on frame sizes 71 to 100  \nFor 24VDC power supply to the brake the control unit BSG is available. With this control unit the same brake release reaction times as with the brake rectifier BGEare attained.
