Frequently Asked Questions
What bearing loads (radial/axial) can this motor tolerate?
The motor’s datasheet in the IndraDyn S planning manual provides permissible radial and axial forces (e.g. axial forces in the range of a few hundred newtons) under specific shaft and bearing constraints.
What precautions should be taken for the 70 Nm holding brake during installation?
Ensure correct brake supply voltage, mounting preload, and alignment — miswiring or misalignment can cause drag or failure to release. Also account for the brake’s added inertia in dynamic torque calculations.
How does a high winding inductance (3,200 mH) influence drive tuning?
The relatively large inductance slows current dynamics, which may require softer current-loop gains and adjustment of torque bandwidth in controller tuning. Poor tuning could degrade response or cause instability at high frequencies.
In what situations might a forced-air (fan or FN) cooling be required instead of natural convection?
If the duty cycle demands high torque at elevated speeds or ambient temperatures exceeding spec, forced cooling (FN) is necessary to avoid thermal overload. The motor type code “–FN” version is available as an option.
What dynamic torque reserve is available beyond continuous standstill torque?
The motor’s maximum torque is 160 Nm, implying a ~2.8× short-term torque reserve above the 57 Nm continuous rating at standstill.
