CLM EC motor main advantages are:

• High reliability (no brush and commutator wear), even at high achievable speeds
• High efficiency. Low mechanical and electronic losses
• Low EMI according to EN standards for industrial and household applications
• Perfect auto-protect controller function design to avoid overheat/current/voltage/power
• Excellent speed stability (1% of rated speed). Open loop and close loop speed control for selection
• Fanless natural convection controller cooling by heat sink
• Intelligent Power Module (IPM) for quiet operation, high torque, smoother shaft rotation, and improved reliability

EC motors are also called Brushless Permanent Magnet DC Motors (BLDC). They are fed through a
DC link with power originating from an AC source. The DC power is then inverted back to AC which
feeds the motor. Strictly speaking they are AC motors but historically they have been classified as
DC. EC Motors are rapidly becoming one of the most popular motor types. They differ from Brushed
Permanent magnet motors in that the magnets are in the rotor instead of the stator, and in the
commutation method which is controlled electronically. EC Motors, therefore, avoid the use of a
commutator and brushes. The stator is normally a classic three phase stator like that of an induction
motor. All this is the case for CLM EC Motors. CLM Motors meet CE, EN61000-6-1, EN61000-6-2,
EN61000-6-3, EN61000-6-4, EN61000-3-2, EN61000-3-3, EN60335-1 requirements
