Frequently Asked Questions
When operating at maximum torque (160 Nm), what current does the motor require and what are the thermal implications?
At 160 Nm peak, the motor draws ~137.7 A (as per your spec), which results in significant loss heating; the liquid cooling must dissipate this to avoid overheating of the windings or insulation.
What installation constraints apply to the shaft coupling, considering it is a plain shaft design?
The plain (zero-backlash) shaft requires clamping sleeves or sets rather than keyed couplings; the driven mass and coupling must be balanced since the motor is balanced with a full key even when a key isn’t used.
What maximum pressure and coolant volume are acceptable in the cooling circuit?
This motor accepts a maximum system pressure of about 3.0 bar and has a cooling duct volume of 0.11 L for the internal channels.
How does the 3,200 mH winding inductance influence current response and control stability?
A high inductance slows current rise (di/dt) during switching and demands stronger drive voltage or larger DC bus to maintain rapid torque changes, and can also help filter high-frequency noise. It also means that drive tuning must carefully consider current control bandwidth to avoid lag.
At what mechanical loads must I worry about bearing lifetime in this motor?
If radial or axial forces exceed the specified limits (per datasheet tables), accelerated bearing wear occurs; under within-limits loading and proper cooling, the grease and bearing life is rated for ~30,000 hours (L10h)
