Satuma Denki BRS5 Drum Type DC Electromagnetic Brakes Drum Type AC-operated DC Electromagnetic Brakes
Made in Japan
Manufacturer : Satuma
Model ; BRS5
The AC operated DC solenoid brake is actuated by supplying AC power to the DC instantaneous strong excitation circuit using a proprietary control box. This is a separate brake, which is released when the power is on and engaged when it is turned off.

Features
1. A brake lining with a contact angle of 60° is adopted.
・Excellent initial braking torque characteristics and easy replacement
2. Automatic vertical gap adjustment of brake lining
・Simple maintenance and inspection
3. Can be manually opened
・This no-voltage actuation bake can be manually opened using a special auxiliary nut (bolt.)
4. Large electromagnetic brakes come with an air damper (which can be optionally mounted to other electromagnetic brakes. Please refer to the note column of each specification/external dimension table for the standard equipment scope.)
・Mounting the air damper helps ensure shockless and low-noise operation.
※Brake coil connections
◎For circuits with 200 V-class input voltage: Parallel
◎For circuits with 400 V-class input voltage: Series

Note 1: See Table 1 (P. 1 and 2) for major ratings
Note 2: The control box is to be separately installed and placed in the operation panel
Note 3: The control box BRD-SC (Fig. 5) cannot be used for both 200- and 400 V-class brakes. (Control boxes of voltages and frequencies other than those listed in Table 1 are special items.)
Note 4: The control box BRD-LC (Fig. 6) is exclusive for each voltage and frequency
Note 5: Brakes BRS5-3550L or larger come with an air damper, which is also optionally available for brakes BRS5-3145 or smaller. (Sub-symbol L is attached to the symbol of electromagnetic brakes with an air damper.)
