When fitted, the 11.0 Nm holding brake securely locks the shaft under power-off or deceleration, allowing safe stops and preventing drift; for emergency stops it needs sufficient braking force margin above load torque. However, brakes add inertia and require energy to release, so control logic and brake drive circuits must accommodate this.

The 110 mm centering diameter determines alignment precision with mating components (flanges, gearboxes, bearings); mismatches here can cause misalignment, vibration, and early bearing or coupling failure. Proper mounting surfaces and tolerances are needed to exploit motor precision and maintain long life.

The keyway allows positive torque transfer without slippage under heavy loads, but it can introduce stress concentrations that require careful design of key size, fit, and lubrication. The shaft seal protects against ingress of contaminants, which is important for maintaining bearing and seal life especially in harsh or dirty environments.

Nominal speed defines the speed at which rated load can continuously be used; beyond that, torque typically falls off because of limitations in heat dissipation and back EMF. In applications needing higher speed, derating or cooling enhancements are necessary; for frequent changes in speed the inertia and drive capability also matter.

Winding resistance impacts I²R losses and heating, inductance affects how fast current (thus torque) can change (affecting acceleration and response), and current limits govern both peak torque and protection against overcurrent. For high acceleration or load change applications, low inductance and robust current provisioning (drive capable) are essential.
