Is NCJ the same as SNR?

NCJ and SNR are used as related compact helical gearmotor naming directions in the available product materials. NCJ should be treated as the main product name, while SNR can be retained as a related naming reference when needed for replacement or old-document communication.

What is the difference between NCJF and NCJT?

NCJF is handled as a flange-mounted NCJ configuration. NCJT is handled as a foot-mounted NCJ configuration. Both belong to the NCJ compact helical gearmotor family and should be confirmed by drawing.

Can NCJ be used for variable-speed operation?

Yes, NCJ can be reviewed with a wide-frequency motor and frequency control. Product data refers to 20–60 Hz full-load operation under specified operating conditions. The inverter, motor type, torque, cooling, and duty cycle should be checked together.

Can NCJ be used with a servo motor?

AQA servo input is listed as an available input direction. Servo motor frame, flange size, shaft diameter, input speed, torque requirement, and control condition should be confirmed before drawing release.

When should RFKS be selected instead of NCJ?

RFKS should be reviewed when the application needs a larger modular reducer platform, higher torque range, more shaft arrangement options, or inline / parallel-shaft / right-angle configurations beyond compact NCJ gearmotor coverage.

When should SNKG be selected instead of NCJ?

SNKG should be reviewed when the application is ceramic glazing equipment or a ceramic line drive position requiring a dedicated bevel-helical geared motor structure.

What information is needed before quotation?

Send output speed, torque, motor power, ratio, mounting form, input form, output shaft requirement, installation position, terminal box position, and working environment. For replacement, send the old model and nameplate photo.

Can Starshine provide drawings and CAD files?

2D drawings and 3D CAD files can be requested after model, ratio, mounting form, motor option, shaft form, and installation position are confirmed.
