The liquid cooling removes ~1.10 kW at nominal loss for enabling the motor to sustain its standstill torque rating without thermal drift. It specifies ~1.5 L/min flow, ~0.8 bar pressure drop, ≤3 bar inlet pressure and 10 K permitted coolant rise for predictable heat rejection.

The M1 encoder is optical, multiturn-absolute with 128 signal periods and 4,096 mechanical revolutions of absolute range for delivering fine interpolated position feedback. Its Hiperface simplifies commissioning and ensures deterministic, noise-resilient analog-sin/cos plus data communication to IndraDrive controllers.

Its 113 A maximum current and a torque constant of 1.40 Nm/A (20 °C) has healthy dynamic torque headroom up to 110 Nm. Its inverter current limits and thermal models prevents demagnetization and preserves insulation class 155 durability.

Its continuous standstill torque is 36.5 Nm with 28.6 A continuous current, while liquid-cooled, continuous standstill current rises to ~47.7 A. It anchors thermal sizing for low-speed feed axes and static force requirements.

Th moderate inductivity attenuates current ripple at PWM frequencies for easing current-loop tuning and reducing copper losses. It also shapes field-weakening behavior at higher speeds to inform controller bandwidth and voltage utilization strategies.
