Frequently Asked Questions

How does the 7.6 mH winding inductivity in MSK100B-0200-NN-M2-BG1-RNNN affect drive behavior and current ripple?

The higher phase inductance attenuates PWM ripple and eases current-loop tuning. It slightly increases electrical time constants, so torque step response depends more on drive bandwidth and commanded acceleration profiles.

Why is an EnDat 2.1 multiturn optical encoder advantageous on MSK100B-0200 for precision axes?

The EnDat 2.1 provides bidirectional digital feedback with diagnostics and storage of motor parameters. Its multiturn absolute feature preserves position through power cycles, enabling homing-free startup and repeatable alignment on MSK100B-0200.

What does “33.0 Nm at standstill, 100 K” signify on MSK100B-0200-NN-M2-BG1-RNNN, and how should designers interpret it?

The 33 Nm value assumes a 100 K winding temperature rise in MSK modeling. For continuous duty, confirm ambient and cooling permit it or derate torque to keep balance.

Where is the MSK100B-0200 typically applied, given IP65 sealing and natural-convection cooling?

The IP65 sealing and convection cooling suit packaging, machine tools and printing equipment lacking ducted airflow. It inused in food-handling and woodworking axes for straightforward B-side cabling and minimal contamination pathways.

How does the electrically released 32 Nm holding brake on MSK100B-0200-NN-M2-BG1-RNNN support vertical or safety-critical axes?

The energizing releases the brake; loss of power engages it to hold load for supporting controlled stops. Its 32 Nm holding torque prevents back-driving during e-stop, maintenance or servo disable states.
