MDS-D-SVJ3/SPJ3 Series Specifications Manual
4-1 Servomotor
(2) Magnetic brake characteristics
< HF Series >
< HF-KP Series >
(Note 1) There is no manual release mechanism. If handling is required such as during the machine core
alignment work, prepare a separate 24VDC power supply, and electrically release a brake.
(Note 2) These are the values added to the servomotor without a brake.
(Note 3) This is the representative value for the initial attraction gap at 20°C.
(Note 4) The brake gap will widen through brake lining wear caused by braking. However, the gap cannot be
adjusted. Thus, the brake life is considered to be reached when adjustments are required.
(Note 5) A leakage flux will be generated at the shaft end of the servomotor with a magnetic brake.
(Note 6) When operating in low speed regions, the sound of loose brake lining may be heard. However, this is
not a problem in terms of function.
