Brushless gear-motor RP62

brushedplanetarycoaxial

Product Overview
KWC Motor RP62 is a 62 mm-class planetary gear motor / gearbox engineered for applications requiring high shaft rigidity and elevated axial load capacity. Standard configuration features a 14 mm output shaft supported by ball bearings, axial load up to 200 N and multiple reduction options across 1–4 stages. Rated torque reaches 30 N·m (momentary up to 90 N·m) for the 4-stage variant.

Key Facts for Engineering Buyers

• Product category: Planetary Gear Motors & Gearboxes
• Model: RP62
• Brand / manufacturer: KWC Motor (Dongguan KWC Machinery Co., Ltd.)
• Typical mechanical highlights: 62 mm gearbox diameter, 14 mm heavy output shaft with ball bearings, axial load 200 N, radial load 300 N

Core Applications & Solutions

• Lead Screw Lifting & Linear Actuators: 14 mm heavy shaft and 200 N axial capacity allow direct coupling to ball screws and linear actuators for standing desks, lift/pushrod systems and positioning stages while maintaining alignment under push/pull loads.
• Industrial Mixing & Large Gates: Suited to mixers, process valves and large rotating or sliding gates where shaft rigidity and momentary shock resistance (up to 90 N·m) mitigate fluctuating torque or wind/shock loads.
