LA/LB & LAS/LBS Linear Actuators LINEAR ACTUATORS:
LA/LB & LAS/LBS Series
LINEAR ACTUATORS, SYNCHRONOUS OR STEPPING

Versatile, rugged LAS and LBS (stepping) and LA and LB (synchronous) motors/actuators offer design engineers an economical choice for the generation of controlled linear motion for pulling, pushing or lifting. The rotor assembly contains a nut which accepts a standard 1 /4" diameter, 16 TPI, RH Acme screw. Rotor nut and screw provide a Class 2G fit.

LAS and LBS Series (stepping) motors have rotor step angles of 7.5 (LAS) or 15(LBS) with linear resolutions of 768 or 384 steps per inch, respectively. They may be driven with the Hurst Stepping Motor Controllers .

LA and LB Series (synchronous), with rotor speeds of 300 RPM (LA) and 600 RPM (LB) have linear travels of 5/16 and 5/8 in./sec., respectively.

All motors are reversible and have die cast end bells and ball bearing construction. Voltages other than those shown as well as 2-phase, bipolar stepping motor windings may be specified.

NOTES
1. Capacitors for LA and LB synchronous motors are required for operation.
2. Standard configuration for stepping motors is bifilar-wound with 6 lead wires. Click here for standard lead wire color code and switching sequence.
3. Actuator screws of lengths longer or shorter than 8" may be specified.
