Linear Motor Selection Reference

Linear stepper motors, also known as screw linear stepper motors and linear linear stepper motors, are linear motion mechanisms that convert rotational motion into linear motion. There are several key factors to consider when choosing a suitable linear motor. STEPPERONLINE provides you with Some important considerations when choosing a linear motor:

Determine System Load

The data in the table below is the maximum supported thrust of each series of linear motors. The size of the motor can be determined according to the required load size. Please also note: The data in the table is not absolute and is for reference only. If you have special thrust requirements, our technical team will develop a customized plan for you.

Motor Linear Running Speed Selection

The running speed of a linear motor is closely related to the lead of the screw. When the screw rotates one revolution, the nut advances one lead distance. In general, a low speed is selected for a screw with a small lead, and a high speed is selected for a screw with a large lead. The lead size also determines the thrust size, so the following two points should also be noted:

Large lead: Small thrust, fast speed;
Small lead: Large thrust, slow speed.
Screw Effective Stroke

Effective Stroke

The maximum distance the nut can run in the linear direction of the screw.

Drive Selection

The selection of a linear motor drive is actually the same as the selection of a stepper motor drive, because a linear motor is essentially a combination of a stepper motor and a screw. Therefore, when selecting a suitable drive, after determining the motor open-loop or closed-loop type, you can select it according to the current and drive voltage of the linear motor. As long as it is within the allowable range of the drive, the drive can drive your motor.
