The high performance range features specialised materials and design to
provide an outstanding torque/inertia ratio within a compact motor housing.
Incorporating new neodymium magnetic material, optimised geometry and
tolerances, these motors are designed to operate at low voltage and current
ratings. Under typical conditions, the high performance motors will deliver
up to twice the torque of standard hybrid stepper motors.

Hybrid stepper motors convert a pulsed
digital input into shaft rotation. T he
shaft speed and angular rotation are
directly proportional to the input
frequency and number of pulses. This
mode of operation is ac hieved as a result
of the toothed structure of both stator
and rotor stack. A full step is the angle
through which an
unloaded motor
shaft will turn w hen
a single pulse is
applied to the stator
windings. The relative numbers of stator and rotor teeth
defines the size of
the step angle.
Hybrid steppers offer high pr ecision,

Typical applications include office

Motor Sizes
Stepper motors are classified accor ding
to the diameter of the motor body in
inches, e.g. size 23 has a diameter
approximately 2.3 inches. Within each
size range there are many different r otor
stack lengths depending on the output
torque requirement.

Performance Characteristics
The characteristic stepper motor performance
curves are shown in the diagram below.
• Pull In Torque is the dynamic torque that
the motor can start, stop and reverse in
synchronism with the input pulse rate.
• Pull Out Torque is the dynamic torque
that the motor can sustain in the same
direction with integrity.
• No Load Response is the maximum
pulse rate at which an unloaded motor
can start, stop and reverse.
• Slew Speed is the pulse rate at which
a motor can run in the same direction
with integrity.
• Holding Torque is the torque generated
when the stator is energised at rated
current.
• Detent Torque is the torque required
to turn the rotor without power applied
to the stator.

Drive Electronics
The performance of a stepper motor is
strongly influenced by the type of drive
used.
Unipolar
A unipolar drive causes current to flow in
one direction only through each section of
winding, in sequence, to create a rotating
field. Stepper motors having 5, 6 or 8 leads
(four individual phases) can be driven from
a unipolar drive. Stepper motors having 5
leads can only be driven from a unipolar
drive.
Can only be driven from a bipolar drive.
Bipolar drives require 4 motor wires and energise
the 2 phases sequentially with alternate polarity.

Notes:
Bipolar
From a bipolar drive, current flows in either
direction through each winding in
sequence. To operate from a bipolar drive,
a stepper motor needs to have two effective
windings, and therefore only requires 4
leads. Motors with 6 or 8 leads can be
converted to 4 leads by making simple
modifications.
Dimensions (mm)
Can be driven from unipolar or bipolar drives.
Custom Requirements
Lead Wires & Connectors
Motors can be supplied fitted with a wide
range of colour coded UL-approved lead
wires and connectors. The leads are fitted
to custom length, with sheathing, heatshrink
or harnesses. Astrosyn can also supply
EMC-compliant braided cabling.

Motor Output Shaft
To avoid damage, drive shaft attachments
must be fitted with care. Astrosyn can
supply motors fitted with pulleys, gears,
gearboxes and custom shafts (e.g., flats,
holes, threads, keyways).
