SDZ1-Y type electromagnetic power-off brakeDetailed product description：

I. Purpose
The SDZ1-Y type electromagnetic power-off brake is a type of brake that uses energized electromagnetic attraction and de energized friction braking. A new type of YEJ series electromagnetic braking three-phase asynchronous motor is mainly generated in conjunction with Y series motors. Widely used in metallurgy, construction, chemical, food, machine tools, packaging and other machinery to achieve fast parking and accurate positioning, and can be used in situations such as safe (emergency) braking during power outages.

2、 Characteristics
This type of brake has the advantages of compact structure, easy installation, wide applicability, low noise, high working frequency, sensitive action, and reliable braking. It is an ideal automation actuator in industrial modernization.

3、 Working principle and installation maintenance
The electromagnetic power-off brake is mainly composed of the excitation part (yoke 1, coil 2, spring 3, armature 4), spline 7, brake disc 8 sets and other main components. The excitation part is installed on the motor end cover 11 by installing screw 10. After adjusting the air gap to the specified value δ by turning the installation screw 10, reverse the hollow bolt 9 and tighten the excitation part. The Huajian set 7 is connected to the transmission shaft through a key; Brake disc 8 and Huajian sleeve 7 are engaged through splines. When coil 2 is powered off, under the action of spring 3, friction is generated between brake disc 8, armature 4, and motor end cover 10, which is transmitted to the drive shaft through spline sleeve 7 to brake the shaft. When coil 2 is energized, under the action of electromagnetic force, armature 4 is attracted towards magnetic yoke 1, causing brake disc 8 to release and the transmission shaft brake to be released. When there is a power outage during equipment maintenance, the brake can be released manually by releasing mechanisms 5 and 6
Before installation, the friction pair surface should be cleaned of oil stains and debris

δ: Recommended value for initial installation air gap

5、 Precautions
1. Friction plates are vulnerable parts. After wear and tear, the air gap increases. When the maximum allowable air gap of the brake is exceeded, it should be readjusted, otherwise it will affect normal operation and even damage the brake and motor.
2. When operating and braking frequently, it is necessary to regularly check whether the fasteners are loose. If they are loose, they should be readjusted and tightened before use.
3. When the brake is installed on the motor, if the motor has difficulty starting or produces noise, the brake should be checked and adjusted according to Article 3 of this manual.

6、 Control circuit
The working voltage of the brake coil is usually two types: DC 99V and 170V. Our factory has ZL and ZL1 rectifier power supplies specially designed for brake systems, with input and output protection circuits, small size, reliable operation, and overall sealing. They can be directly installed in the junction box of the motor. The wiring method is detailed in the ZL rectifier power supply wiring diagram.
