The brake can hold the load when unpowered or during fault conditions, but when releasing/engaging it adds delay and transient torque pulses—your drive must ramp gently to prevent jerks or overshoots. Also, the brake power consumption and heat need to be accounted for in machine safety design.

The 130 mm centering diameter demands precise mounting surfaces (low runout, flatness) to avoid bearing loads or vibration; misalignment will amplify stress on coupling and shaft. Use a precision hub and alignment method to preserve concentricity, especially at high rpm.

Because it remembers the absolute position over multiple revolutions, the system can resume exact angular referencing after power cycle without homing routines. But you still must ensure no mechanical slip or backlash occurred while powered down, or the physical position may drift.

A keyway introduces stress concentrators and slight imbalance, so dynamic balancing is essential to avoid vibration. The shaft seal helps guard against contamination but also adds drag and heat—ensure the seal is rated for your rpm and environment.

Matching or “inertia ratio” between motor rotor and load matters: if load inertia is much higher, responsiveness suffers; if too low, overcontrol or vibration may occur. Use a coupling or mechanical transmission to bring the effective inertia into an acceptable ratio (often between 1:3 and 3:1).
