What radial or axial loads on the shaft are acceptable without shortening bearing life?

The motor’s project planning manual provides permissible radial and axial force limits depending on frame size—exceeding them reduces bearing L₁₀ life.

How does the multiturn absolute optical encoder (Hiperface) benefit closed-loop precision?

Because it provides absolute multi-revolution position immediately at power-up, you avoid homing routines and ensure deterministic positioning.

What considerations apply if I retrofit this motor into an existing machine using a clamping hub coupling?

Because the shaft is plain (no key by default), use a zero-backlash clamping sleeve or hub coupling to avoid introducing shock loads to the shaft.

What is the practical impact of the 3,200 mH winding inductance on control behavior?

A large inductance smooths current ripple and helps reduce torque ripple, but it slows response to fast current commands—limiting the achievable current slew rate.

How does using natural convection cooling affect continuous operation at high loads?

Without forced cooling, the motor’s internal temperature must be kept within limits via ambient airflow; hence continuous torque must be derated if ambient temps exceed spec or ventilation is restricted.
