| Dimension |
※ The Dimension are for eccentric gear box closed loop stepper motor， refers to eccentric gear box；
※ We can formulate the electrical parameters of the eccentric gearbox closed-loop stepper motor according to your needs, or replace it with a planetary gearbox or add a power-off brake, etc；
※ When installing the closed-loop stepper motor of the eccentric gearbox, be sure to use the front end cover of the motor for installation and positioning, and pay attention to the tolerance matching to strictly ensure the concentricity between the output shaft of the closed-loop stepper motor of the eccentric gearbox and the load.

| Speed - Torque Characteristics |
※ Speed Torque Characteristics are data based on our company's measurement conditions. When conditions change, Speed Torque Characteristics may change.
※ Gearbox Closed-loop Stepper Motor can generate a lot of heat due to different driving conditions. To protect the encoder, use a closed-loop stepper motor when the case temperature is below 85°C.

| Precautions For Cables |
|
| |
When plugging and unplugging the connector, be sure to hold the connector for operation。 If you pull on the cable, it may cause poor contact。 | Do not bend the cable at the connector part, if stress is applied to the connection part or the terminal, it may cause poor contact or disconnection。 Please fix the red two connector parts to prevent the connector parts from shaking, which may cause terminal damage or poor contact。 | |
|
| |
When plugging in the connector： Hold the connector body and insert it straight。 If inserted at an angle, it may cause terminal damage or poor contact。 When unplugging the connector： Please unlatch the connector first, then pull it straight out。 If you hold the cable and pull it out, the connector may be damaged。 | Please use the appropriate length for wiring so that the cable will not be pulled when moving. In addition, please make sure that the bending radius R is above the cable diameter of 6. |
