Product overview
The KST CM633 from KST Meizhou Company Limited is a programmable Clubman servo. Its mechanical construction combines an aluminum-alloy case, a coreless DC motor, metal gears and two ball bearings, with a potentiometer serving as the position sensor. Case dimensions are 33mm × 15mm × 30mm ±0.2mm, and weight is 35g ±10%. The default travel setting provides ±50° of movement, or 100° total. Soft start is programmable, alongside the servo’s stated programmability.
The CM633 has a rated voltage of DC7.4V and a supply range of DC4.8V–8.4V, with a working-frequency specification of 1520us/333Hz. At 7.4V, torque is 13.8Kgf.cm, speed is 0.09sec/60° and start current is 2.95A. The voltage-specific ratings range from 9.00Kgf.cm and 0.14sec/60° at 4.8V to 15.0Kgf.cm and 0.08sec/60° at 8.4V. Start current at those endpoints is 1.85A and 3.25A, respectively. The temperature range is -10°C to +65°C.
