Frequently Asked Questions
How should I size loads given the electrically released 70 Nm holding brake?
Use the brake only to hold position at standstill or during power-off—Rexroth states it is not a service brake or personnel safety device. Verify static load torque (including gravity) plus safety factor stays below 70 Nm at the motor shaft.
Does the keyed shaft change coupling selection or alignment practices?
Yes, these motors are balanced “with key,” and stiff couplings or misalignment can overload bearings; use an axially compensating coupling and observe shaft load limits. The key itself is not supplied and must match DIN 6885.
What enclosure and environmental limits should I assume for panel layout?
MSK motors are IP65 with insulation class F and specified 0…40 °C ambient during operation, so avoid direct wash-down or high-heat enclosures without derating. Plan cable routing and seals accordingly to maintain the IP degree of protection.
How does the 3.2 H class winding inductivity influence the drive selection and dynamics?
Higher inductance reduces current ripple and can ease EMC/filtering but slows current loop response, so tune the current controller accordingly and ensure the drive’s voltage and switching strategy can deliver commanded dynamics. Match the IndraDrive capability to the motor’s current and voltage needs.
What are good B2B applications for this motor’s torque profile and encoder?
High-inertia axes in packaging, printing, or robotics benefit from the high peak torque for fast indexing and the absolute multiturn feedback for zero-reference startups. Ensure the machine duty doesn’t exceed natural-convection thermal limits or move to fan/FN cooling.
