MoToR ConnECTIonS
Motor connections are of two types for brushless motors: phases and Halls. For brush motors, only the armature connections are needed. The phase
or armature connections carry the amplifier output currents that drive the motor to produce motion. The Hall signals are three digital signals used for
commutating a brushless motor. when using a brush motor the Hall inputs should be unconnected and the motor armature connections made between
the U & V phase outputs.
MoToR PHASE ConnECTIonS: BRUSHlESS
The amplifier output is a three-phase PWM inverter that converts the DC buss voltage
(+HV) into DC voltage waveforms that drive two motor phase-coils at a time (trapezoidal
commutation). Cable should be sized for the continuous current rating of the amplifier. Motor
cabling should use twisted, shielded conductors for CE compliance, and to minimize PwM
noise coupling into other circuits. The motor cable shield should connect to motor frame and
the equipment frame ground for best results.
MoToR PHASE ConnECTIonS: BRUSH
The amplifier output is an H-bridge PWM inverter that converts the DC bus voltage (+HV) into a
DC voltage waveform that drives the motor armature. Cable should be sized for the continuous
current rating of the amplifier. Motor cabling should use twisted, shielded conductors for CE
compliance, and to minimize PwM noise coupling into other circuits. The motor cable shield
should connect to motor frame and the equipment frame ground for best results.
MoToR HAll SIGnAlS
Hall signals are single-ended signals that provide absolute feedback within one electrical cycle of
the motor. There are three of them (U, V, & W) and they may be sourced by magnetic sensors in
the motor, or by encoders that have Hall tracks as part of the encoder disc. They typically operate
at much lower frequencies than the motor encoder signals, and are used for commutation.
when driving DC brush motors, the Hall inputs should be left unconnected.
