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, open loop position control with

excellent acceleration performance. Typical applications include office equipment, medical instrumentation, factor y automation, vending and ticketing equipment. This Product Guide lists the dimensions and average performance characteristics of our standard range.
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.

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.
