The 40 mm centering diameter presumes mating hardware and mounts that match that spindle for concentricity; misalignment can cause vibration or bearing wear. The keyway shaft simplifies torque transmission to couplings or gears but requires the correct key and tolerances per standard (e.g. DIN keyway), and care in mounting to avoid keyway stress concentrations.

The side-A connection implies the cable exits on the designated side (matching drive/mounting layout), so the cable routing and space constraints must consider bend radius, drag chains, etc. The coupling unit needs proper mating connectors and possible shielding if used in electrically noisy environments; connector type and pin-outs must match the drive’s requirements.

Standard balancing typically means the rotor is balanced sufficiently for most applications but may not meet requirements for ultra-high speed, extremely low vibration, or precision optics/semiconductor handling. For those, “high precision” or “high balancing grade” versions might be needed to reduce runout and micro-vibrations.

Because this motor is designed for digital drive controllers and provides resolver + absolute encoder feedback, the drive must support those feedback types, have sufficient current capacity, and be able to handle the thermal and dynamic requirements (peak currents, braking regen, inertia). Controller firmware must also support the encoder protocols, possibly calibration (offset, scaling), and safety features tied to the holding brake.

The 1.0 Nm brake allows the rotor to stay locked under small torques when de-energized, which is useful for safety or position hold, but it adds inertia and requires extra torque from the motor during braking/unbraking cycles. Also the brake consumes power (for example to release) and may produce heat, so thermal load and control wiring need to be planned accordingly.
