Brake Voltage Supplied from the Motor
There are specific instances when the brake yoltage can be tapped from the motor’s terminal block. The adyantage ofbrake systems wired in this way iwhen poweris applied to the motor, the brake releases, (requiring no additional brake supply power wiring). The brake can be wired to the motor terminablock 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 age are or normal brake reaction time. For raid brake reaction time. incororate the contact as shown on the brake diagram located on the inside of the motor conduit box lid.
in the continuous released state the curent losses are reduced to the necessarvy minimum so the thermal loadine of the brake is verv low
The use of the BGE Brake Rectifier is recommended if:
Short brake release reaction times are required
High starting frequencies are encountered.
High ambient temperature is present or the brake is reguired to be in the continuous released state while the motor is at rest or operating at low speds
Brake Connection (AC Voltage)SEW-Eurodrive motor brakes can be connected in a number of different ways. In order to connectthe brake for each application, it is important to refer to the data on the motor nameplate that describes the brake system. The brake fields are: brake voltage, brake torque and brake control.
This operating instruction covers AC brake voltages with the following brake control componentsIf the brake voltage is DC, or if the brake control components differ from those listed below, an ad-ditional operating instruction must be consulted for connection information.
SEW-Eurodrive fai-safe mechanical brakes are DC controlled. Standardly, a brake rectifierhalfwave) is provided to convert the AC line voltage to the DC volae required to drive the brake. 24VDC brakes do not include a rectifer. When voltWhen yoltage (V) is removed from the brake. it will set.age ( Ve) is applied to the brake, it will release.
The brake rectifier can be wired either for normal brake reaction time (setting, stopping) or fast brake reaction time.
The wiring diagrams for brake connections are located on the inside of the motor conduitbox lid, The brake will release and allow the motor to rotate when the nameplate ACbrake volage V, is supplied to the brake rectifier terminals. There are certain cases where the brake rectifier can receive its voltage from the motor’s ter-minal block, meaning that when power is applied to the motor it will simultaneously release the brake and start the motor.
SEW products are transmission equipment in basic industries, including reducers, reducers and frequency converters. SEW’s products use a new “module combination” concept to provide a broader space for the development of electromechanical and electronic integration. Various machinery and equipment, including steel, metallurgy, cement, mining, infrastructure, building materials, environmental protection, papermaking, ports, airports, aviation, aerospace, petrochemicals, light industry, food and beverage, warehousing and logistics, etc. SEW’s products are widely used in key national engineering projects, such as major domestic ports, the Capital Airport and major domestic airports, and major sewage treatment projects; China Millennium Monument, Capital Theater, and the Great Hall of the People’s Large and Small Auditorium Renovation Projects ; Tianjin FAW, China FAW, Shanghai GM, Volkswagen, SAIC-GM-Wuling; Shanghai Maglev Train Project, Three Gorges Water Conservancy Project, Shenzhou Satellite Launcher Project; Ground Stage Drive System for the Opening Ceremony of the 29th Beijing Olympic Games, Main Torch Bearer Aerial Walk Drive System wait.
