Product overview
The KST A12-T from KST Meizhou Company Limited is a wing servo built around a seven-phase coreless DC motor. Its case measures 30 × 12 × 35.5 mm with a stated tolerance of ±0.2 mm, and its weight is 32 g ±10%. The default travel extends 60° in each direction for 120° total movement. Electrical specifications comprise a rated voltage of DC7.4V, a DC6.0V–8.4V voltage range and a working-frequency rating of 1520us/20 K Hz.
The A12-T has three voltage-specific torque and speed ratings. At 6.0V, torque is 1.6 N.m and movement takes 0.15 seconds per 60°. At the rated 7.4V supply, torque is 1.8 N.m and speed is 0.13 seconds per 60°. At 8.4V, the corresponding figures are 2.0 N.m and 0.12 seconds per 60°. Across these ratings, higher supply voltage corresponds to greater torque and a shorter movement time. The specified temperature range is −10°C to +60°C.
