Kechen Motor – 775 DC Motor Manufacturer in China
775 motors are widely used in handheld tools, conveyor drives, robotics, and battery‑powered equipment. Unlike generic DC motors that force you to redesign your mounting plate or wiring harness, a properly specified 775 series motor should match your existing mechanical envelope while delivering predictable torque and speed under load. Our 775 motors use a drawn steel housing with a nickel‑plated finish to resist corrosion in shop environments where coolant mist, dust, or humidity is present. The rotor windings are machine‑wound with double‑insulated copper wire rated for Class F (155°C) thermal protection, giving you a safety margin even when the motor runs near its continuous duty limit. We offer 12V and 24V variants with no‑load speeds ranging from 6,000 RPM to 12,000 RPM and stall torque up to 1.0 N·m at 24V. Each unit uses either a 5‑pole or 7‑pole armature depending on the version, paired with sintered bronze or ball bearings. These motors can be installed in plastic housings, metal chassis, or enclosed gearboxes without overheating, and they meet CE and RoHS requirements for commercial and light industrial applications.
Custom 775 DC Motor – Your Voltage, Shaft, and Connector
Our 775 series focuses on the details that reduce field failures and simplify integration. The commutator undergoes a diamond‑turning process to lower arcing and sparking, especially during sudden startups or frequent direction changes. We use high‑grade carbon brushes with pigtail leads rather than cheap spring‑loaded types, so brush life typically exceeds 500 hours under normal continuous load, with longer life in intermittent duty applications. The housing includes pre‑drilled M3 mounting holes on a standard 29mm bolt circle, making it a direct replacement for most existing 775 footprints. For thermal management, the stator incorporates ventilation slots that allow airflow without letting debris inside. You can choose between 3.17mm, 5mm, or 6.35mm shafts, and we can grind a flat or add a circlip groove per your drawing. Wire leads are 22 AWG with silicone insulation that stays flexible from -20°C to 120°C, and we can pre‑solder filtering capacitors across the terminals for applications sensitive to electromagnetic interference. Custom connectors (Molex, JST, or bare tinned ends) are available with a minimum order of 200 pieces. Instead of claiming unrealistic performance, we publish realistic curves for torque, current, and efficiency, and we sample each production lot following ANSI/ASQ Z1.4 to verify no‑load current and speed before shipping.
