NEMA 17 Linear Actuator

Hybrid Stepper Motor Linear Actuator

LM17 NEMA 17 1.5 A 1.8° Non-captive Linear Stepper Motor


NEMA 17 (42 mm) 1.5 A, 1.8° non-captive linear actuator stepper motor delivering a maximum thrust of up to 50 lbs (22 kg)

Specifications

Force -speed performance

Screw A — 0.25″/6.35 mm travel per revolution
Screw B — 0.125″ / 3.175 mm travel per revolution
Screw C — 0.063″ / 1.588 mm travel per revolution
Test conditions

100% current with damper simulating load.

Load limits

Non-captive shaft linear actuators limit is 50 lbs / 22 kg. External shaft linear actuators limits are determined by the selected nut.

NOTE: Above performance data for maximum force/load is based on a static load and will vary with a dynamic load

Leadscrew maintenance statement

While under optimal conditions lubrication interval is expected to occur approximately once every 1000 hours of service. Actual life will depend on application and environment. Based upon this, frequent inspections must be performed and a maintenance interval determined based on actual conditions.

Recommended lubricant: Dupont Krytox GPL 206
