What is a Brushless DC motor (BLDC)?
A brushless DC motor (known as BLDC) is a permanent magnet synchronous electric motor which is driven by direct current (DC) electricity and it accomplishes electronically controlled commutation system (commutation is the process of producing rotational torque in the motor by changing phase currents through it at appropriate times) instead of a mechanically commutation system. BLDC motors are also referred as trapezoidal permanent magnet motors.
It has no mechanical commutator and associated problems
High efficiency due to the use of permanent magnet rotor
High speed of operation even in loaded and unloaded conditions due to the absence of brushes that limits the speed
Smaller motor geometry and lighter in weight than both brushed type DC and induction AC motors
Long life as no inspection and maintenance is required for commutator system
Higher dynamic response due to low inertia and carrying windings in the stator
Less electromagnetic interference
Quite operation (or low noise) due to absence of brushes
a. High Torque to inertia ratio&up to 25000Nm/kgm² |
b. Fast dynamic response *time constant <20ms |
c. Wide speed adjusting&feedback up to 1000:1 |
d. Steady speed precision up to 0.5% |
e. High overload,2Mn/30s,3.5N.m/10s |
f. Small volume and light |
g. Silent,the lowest noise is only 45dB(A) |
h. Protected with IP65,Class F insulation |
