Technical data
External Drive Motor (R) Appearance and Installation Dimensions

Appearance and installation dimensions of through shaft (S) motors

1. The following are representative products only, and can be made separately according to requirements.
2. The electrical parameters of the motor, winding specifications, and the size and shape of the output shaft can be customized according to your requirements.
3. The standard product is a 1.8° 4-wire motor. 8 lines and step angle of 0.9° are optional if required by customers.
4. The power-off brake can be matched according to your requirements.
Explanation of technical terms
Accuracy: The difference between the theoretical distance traveled based on the lead and the actual distance traveled
Axial load: the axial load aligned with the centerline of the screw
Back-driving force: A push-pull force applied axially causes the nut or screw to rotate
Backlash: Axial clearance between screw and nut
Dynamic load: the load that the screw rod bears when it moves
Screw lead: the axial travel distance of the nut when the screw rotates once
Pitch: the axial distance between adjacent threads
Radial load: load perpendicular to the centerline of the screw
Resolution: the straight-line distance that a pulse screw motor drives the load to move
Resonance: Unstable vibrations produced by a mechanical system
Static load: the load applied to the screw when the screw is at rest
Step length: the straight-line distance that the system moves when the motor takes a full step
Nut size
Dimension of round Flange nut

Size of Flange nut cut on both sides

Notice
1. When the motor is connected to the driver, please do not connect the wrong phase.
2. Due to different driving conditions, the motor may have obvious heat. The surface temperature of the motor must not exceed 85°C during operation.
3. When installing the motor, be sure to use the front end cover of the motor to install the spigot for positioning, and pay attention to the tolerance fit to ensure the concentricity of the motor shaft and the load.
Application
There are four types of motor lengths for the 2 Phase Nema 34 Trapezoidal stepper motor: 80mm, 94mm, 118mm, and 150mm. It is recommended to use FYDM808T for the adapter drive model. The 2 Phase Nema 34 Trapezoidal stepper motor comes in two different shapes, as well as nuts with circular flanges and double cut flanges for users to choose from. The 2 Phase Nema 34 Trapezoidal stepper motor uses a stepper motor as the rotational power source and converts rotational motion into linear motion through a helical transmission. It is widely used in many high-precision requirements, including manufacturing, precision calibration, precision fluid measurement, and precise position movement.
