Frequently Asked Questions
What does the 1.70 Nm/A torque constant imply for drive sizing and current limits on MSK100A-0300-NN-M1-AG1-NNNN?
Its torque constant links commanded current to developed torque for simplifying current-loop tuning and anti-windup strategies. Its 1.70 Nm/A can predict saturation margins, choose appropriate current limits and maintain commanded acceleration while minimizing thermal stress on the inverter and motor windings.
Why is natural-convection cooling practical for this motor’s envelope and duty profiles?
The natural convection eliminates blower plumbing and failure points for keeping thermal characteristics stable for moderate continuous loads and frequent accelerations. It also eases enclosure integration and hygiene compliance in food/packaging cells where external fans are undesirable or restricted by washdown practices.
How do 11,200 mH winding inductivity and 4.6 nF leakage capacitance influence EMC and current ripple?
The inductivity smooths phase current for lowering di/dt stress and torque ripple under PWM. Its small leakage capacitance reduces conducted noise paths, while combined with shielded cabling and proper grounding, it supports compliance to industrial EMC limits without excessive external filtering.
How does the 32 Nm electrically-released holding brake on MSK100A-0300-NN-M1-AG1-NNNN aid vertical-axis safety?
The brake engages on power loss to prevent load drift for meeting retention needs on Z-axes or indexing tables. Its electrically releasing it during motion avoids residual drag, while the rated torque simplifies SIL/PL calculations alongside mechanical reduction and frictional holding contributions.
What are the integration benefits of the A-side power connector and plain-shaft geometry on MSK100A-0300-NN-M1-AG1-NNNN?
The A-side power simplifies cable routing in multi-motor frames for improving separation from feedback lines. Its plain-shaft profile accommodates collet, clamp or keyless hubs for minimizing backlash interfaces and easing service swaps without remachining couplers or end effectors.
