6.0 THEORY
6.1 DESCRIPTION OF AC MOTOR OPERATION
Three phase AC motors are comprised of two major components, the stator and the rotor. The
stator is a set of three electrical windings held stationary in the motor housing. The rotor is a
metal cylinder, fixed to the motor drive shaft, which rotates within the stator. The arrangement
of the stator coils and the presence of three phase AC voltage give rise to a rotating
magnetic field which drives the rotor. The speed at which the magnetic field rotates is known
as the synchronous speed of the motor. Synchronous speed is a function of the frequency at
which the voltage is alternating and the number of poles in the stator windings.
The following equation gives the relation between synchronous speed, frequency, and the
number of poles:
Ss - 120 f/p
Where: Ss = Synchronous speed (rpm), f = frequency (Hz), p = number of poles
In three phase induction motors the actual shaft speed differs from the synchronous speed as
load is applied. This difference is known as “slip”. Slip is commonly expressed as a percentage
of synchronous speed. A typical value is three percent at full load.
The strength of the magnetic field in the gap between the rotor and stator is proportional
to the amplitude of the voltage at a given frequency. The output torque capability of the
motor is, therefore, a function of the applied voltage amplitude at a given frequency. When
operated below base (rated) speed, AC motors run in the range of “constant torque”. Constant
torque output is obtained by maintaining a constant ratio between voltage amplitude (Volts)
and frequency (Hertz). For 60 Hz motors rated at 230, 460, and 575 Vac, common values
of this V/Hz ratio are 3.83, 7.66, and 9.58 respectively. Operating with these V/Hz ratios
generally yields optimum torque capability. Operating at lower ratio values results in lower
torque and power capability. Operating at higher ratio values will cause the motor to
overheat. Most standard motors are capable of providing full torque output from 3 to 60 Hz.
However, at lower speeds, where motor cooling fans become less effective, supplemental
cooling may be needed to operate at full torque output continuously.
If the frequency applied to the motor is increased while the voltage remains constant, torque
capability will decrease as speed increases. This will cause the horsepower capability of the
motor to remain approximately constant. Motors run in this mode when operated above
base speed, where drive output voltage is limited by the input line voltage. This operating
range is known as the “constant horsepower” range. The typical maximum range for constant
horsepower is about 2.3 to 1 (60 to 140 Hz). The diagram on the next page depicts the
characteristics of a typical AC induction motor with a 60 Hz base speed.
Consult motor manufacturer before operating motor and/or driven equipment
above base speed.

6.1.1 VARIABLE TORQUE VS. CONSTANT TORQUE
Variable frequency drives, and the loads they are applied to, can generally be divided into
two groups: constant torque and variable torque. Constant torque loads include: vibrating
conveyors, punch presses, rock crushers, machine tools, and just about every other
application that is not considered variable torque. Variable torque loads include centrifugal
pumps and fans, which make up the majority of HVAC applications.
Variable torque loads are governed by the affinity laws, which define the relationships
between speed, flow, torque and horsepower. The diagram below illustrates these relation-
ships:

“Variable torque” refers to the fact that the torque required varies with the square of the speed.
Also, the horsepower required varies with the cube of the speed, resulting in a large reduction
in horsepower for even a small reduction in speed. It is easily seen that substantial energy
savings can be achieved by reducing the speed of a fan or pump. For example, reducing
the speed to 50% results in a 50 HP motor having to produce only 12.5% of rated horsepower,
or 6.25 HP. Variable torque drives usually have a low overload capacity (110% - 120% for 60
seconds), because variable torque applications rarely experience overload conditions. To
optimize efficiency and energy savings, variable torque drives are usually programmed to
follow a variable V/Hz ratio.
The term “constant torque” is not entirely accurate in terms of the actual torque required for
an application. Many constant torque applications have reciprocating loads, such as vibrating
conveyors and punch presses, where the rotational motion of the motor is being converted to
a linear motion. In such cases, the torque loads, this fluctuation in torque is not a direct
function of speed, as it is with a variable torque load. As a result, constant torque drives
typically have a high overload rating (150% for 60 seconds) in order to handle the higher peak
torque demands. To achieve maximum torque, constant torque drives follow a constant V/Hz ratio.
SpinMaster™ PowerWash drives have full overload capacity (150% for 60 seconds, 180% for
30 seconds), so that either one can be used for either type of application. The V/Hz ratio can
also be changed to optimize performance for either type of application.
6.2 DRIVE FUNCTION DESCRIPTION
The SpinMaster™ Micro Series Drives are a 16 bit microprocessor based, keypad
programmable, variable speed AC motor drive. There are four major sections: an input diode
bridge and filter, a power board, a control board, and an output intelligent power module.
6.2.1 DRIVE OPERATION
Incoming AC line voltage is converted to a pulsating DC voltage by the input diode bridge.
The DC voltage is supplied to the bus filter capacitors through a charge circuit which limits
inrush current to the capacitors during power-up. The pulsating DC voltage is filtered by the
bus capacitors which reduces the ripple level. The filtered DC voltage enters the inverter
section of the drive, composed of six output intelligent insulated gate bi-polar transistors
(IGBTs) which make up the three output legs of the drive. Each leg has one intelligent IGBT
connected to the positive bus voltage and one connected to the negative bus voltage.
Alternately switching on each leg, the intelligent IGBT produces an alternating voltage on each
of the corresponding motor windings. By switching each output intelligent IGBT at a very high
frequency (known as the carrier frequency) for varying time intervals, the inverter is able to
produce a smooth, three phase, sinusoidal output current wave which optimizes motor
performance.
6.2.2 CIRCUIT DESCRIPTION
The control section consists of a control board with a 16 bit microprocessor, keypad and
display. Drive programming is accomplished via the keypad or the serial communications port.
