Why Are Coreless Motors Widely Used in Medical Devices?
Motion systems designed for medical applications have vastly different priorities than industrial equipment. In a handheld surgical tool or a portable analyzer, motion smoothness, low vibration, and thermal stability often matter far more than raw power. Coreless DC motors are frequently used in these applications because their ironless rotor design provides very low inertia and […]
Why Voltage Ripple Affects Mini BLDC Motors?
Many portable device teams see unstable motor behavior even with a perfectly good motor. This often manifests as startup jitter, sudden speed changes, or unexpected noise, derailing development timelines. Miniature BLDC motors are highly sensitive to power supply quality because their low rotor inertia and rapid electronic commutation instantly translate any voltage instability into mechanical […]
What Causes Noise in Brushless DC Motors?
Many OEM engineers run into unexpected noise during device integration, a problem that can delay projects and undermine user confidence. This noise rarely indicates a defective motor; instead, it’s a symptom of a system-level electromechanical issue. The primary causes of noise in BLDC motors are electrical commutation ripple and mechanical imbalances. Our engineering approach is […]
