Frequently Asked Questions
How does the motor’s high inductance (3,200 mH) affect drive bandwidth and current dynamics?
The large inductance slows current change (di/dt), limiting achievable acceleration unless the drive compensates with higher voltage or advanced current control loops.
In what way does the liquid cooling capability influence continuous versus peak torque duty cycles?
Because the motor can dissipate heat more efficiently, it can sustain higher continuous torque for longer without thermal shutdown or derating compared with air-cooled versions.
What mounting considerations or restrictions exist due to the plain shaft design?
You must use a clamping hub, clamping sleeve, or zero-backlash coupling, and avoid exceeding radial/axial load limits to prevent bearing damage.
How should coolant pressure and flow be sized for a system using this motor?
The motor supports up to 3.0 bar coolant pressure, and its coolant duct volume is about 0.11 liters, so design the pump and plumbing to exceed those minima
What limitations might you encounter in high-acceleration axes due to the motor’s shaft load capacity?
Exceeding permissible radial or axial forces (as given in the manual) may drastically reduce bearing life or cause mechanical failure.
