NEMA14 captive stepper motor with lead screw holding torque 0.2kg tr8*8 for madical equipment

The NEMA14 captive stepper motor you mentioned is designed with a lead screw and has a holding torque of 0.2kg. The lead screw specification you provided is TR8*8. Here's what this information implies:

Motor Type: 2-phase stepper motor
Holding Torque: 0.2kg (kilograms)
Lead Screw: TR8*8

The holding torque indicates the maximum torque the motor can exert while stationary to prevent movement, typically measured in N.m (Newton-meters) or kg.cm (kilogram-centimeters). In this case, it is specified as 0.2kg, which means the motor can hold objects weighing up to 0.2kg without rotating when power is applied.

The lead screw specification TR8*8 refers to the thread type and pitch of the lead screw. TR8 indicates a trapezoidal thread profile with an 8mm major diameter. The "*8" indicates that the lead screw has a pitch of 8mm, meaning it advances by 8mm for each complete revolution.

This type of stepper motor with a captive lead screw is commonly used in medical equipment, such as medical pumps, precision positioning systems, or other applications where controlled linear motion is required.

Features:

• Bipolar or unipolar versions available

• Hybrid stepper construction

• Available in single or double shaft versions

• CE and RoHS approved

• Customizations on request
