Higher resistance leads to I²·R losses, so under heavy continuous load the motor will heat significantly; good cooling (natural or surface) and accurate current control are important to avoid thermal drift or damage. Resistance will also rise with temperature, reducing torque output slightly and increasing losses.

Without a blocking (or holding) brake, the motor cannot indefinitely hold a vertical load in position when power is lost; external mechanical brakes or counterbalances will be needed for safe stops or emergencies. For applications with frequent starts/stops or vertical loads, this increases system complexity.

DSF enables high resolution position/velocity control with faster commutation and lower jitter, improving responsiveness and reducing positional error, especially at low speed. However, it may require more complex wiring, shielding, and compatible controller electronics.

The continuous torque at standstill is limited by thermal capacity, winding heating, and mechanical stresses; running at max torque continuously would overheat windings or bearings. The “maximum theoretical” torque is a short-term or peak value, often used during acceleration or intermittent load, not for long durations.

The motor’s rotor inertia acts against acceleration—higher inertia means slower acceleration/deceleration, requiring more torque or sophisticated control. For applications needing rapid direction changes or short cycle times, minimizing inertia (or using external coupling, gearing) matters.
