-
Harsh-environment robotics
Structural Features:
-
IP54 sealed housing with shaft seal
-
Brake assembly mounted on non-drive end
-
Resolver mounted rearward, ruggedized against shock
Working Principle:
Standard PMSM operation with resolver providing analog position signals (sine/cosine) demodulated by the drive to derive absolute commutation and incremental position information.
Installation Requirements:
-
Brake must be wired to a monitored 24 VDC supply with sufficient current
-
Resolver excitation wiring must be shielded and matched impedance
Usage Precautions:
-
Brake releases only when powered; ensure emergency fallback in power loss
-
Resolver coupling not to be stressed mechanically
