PWM Motor Control Description

PWM Motor Control is accomplished when pulse width modulation is used to regulate a current transmitted to a motor.  The PWM Motor Control emits a current that is smoother and at a higher switching frequency.  The advantage to this is that it is inaudible to humans.  This eliminates any hum otherwise heard at lower frequencies.  One exception is that some controllers for models that are radio controlled deliberately produce audible sound as beeps. 

PMW Motor controllers generally include one large reservoir capacitor and switching elements (thyristors, transistors or Mosfets) in an H-bridge configuration.  An H-bridge allows voltage to be moved across a load either direction.  The term comes from the graphic diagram of such a circuit where it appears like an "H".  They may be assembled from separate parts or produced as integrated circuits.  A common use is in robotics where DC motors may run forward or backward.  An H-bridge may also be used in braking a motor.

A PWM Motor Control Creates A Sine Wave Pattern

PMW Motor Controls as in the adjustable frequency drive, use a series of pulses at the same amplitude, but varying width, to create an artificial sine-wave pattern.  This pattern of electrical power is then used in AC motors to drive the motor just as if it were generated from a normal AC source.  The sine waves result from the combination of the action of producing the varying width pulses and their resulting influence in creation of electrical flux in the motor.  The flux does not instantly dissipate and tends to resist change, so the pulses from a PMW Motor Control are "rounded off" into the sine pattern.  Further conditioning is usually done by employing capacitors to enhance the smoothing of the curves.

PWM Motor Control DC Motors

The PMW Motor Control can also be used with DC motors.  In this case the duration of the pulses is directly proportional to the DC voltage value.  The supply voltage determines the speed of the motor.  By controlling the duration of pulses the actual voltage received can be raised or lowered.  If the pulses are delivered fast enough, the motor will not seem to register the fact that the pulses are not continuous.  The motor will only turn as fast as the proportion of the actual voltage in relation to maximum voltage.  If voltage is 6V a 12V motor will turn at half speed.  It is an extremely efficient circuit as almost none of the power will be lost in the circuit. 

Other characteristics of this form of PWM Motor Control are:

  • Protection against short circuit and overload

  • A PMW range adjustable from 0-100%

  • Frequency is adjustable

  • High efficiency
