LK-TECH MG4010E-i10 V3 Servo Motor
LK-TECH MG4010E-i10 V3 is a BLDC servo with a PG4210 10:1 planetary reducer and built-in driver, available as a CAN or RS485 version. At 24 V it gives 2.5 N·m rated and 4.5 N·m max, 260 rpm rated and 320 rpm max, 140 W. It has an 18-bit motor encoder plus a 14-bit output encoder, ≤ 8 arcmin backlash, torque / speed / position loops, a 7.4–32 V supply, Ø53 × 41 mm and 250 g.

- Continuous rated torque
- 2.5 N·m
- Rated-load speed

Stall torque and current are not continuous ratings. Check the duty cycle and starting load when choosing the driver and power supply.
Thermal limits by level
Product operating conditions, chip ambient ratings, package case limits and junction maxima remain separate.
