Product overview

The Flash Hobby M45CHW Coreless Servo combines a coreless motor with digital control in a standard servo format. Its construction uses high precision steel gears, dual ball bearings and a fully CNC-machined AL6082 aluminium housing and structure. The waterproof servo measures 40x20x40.50mm and weighs 75g without a servo horn. Electrical connection is through a 300mm lead with a JR plug and 22AWG wire, with brown identifying negative and red identifying positive.

The M45CHW operates from 6.0V to 8.4V and across temperatures from -20°C to +60°C. Maximum torque is 35kg-cm at 6.0V and 45kg-cm at 8.4V; corresponding no-load speeds are 0.12sec/60° and 0.11sec/60°. PWM control uses a 1500usec center point, with a 2 usec dead band at both test voltages. Operating travel is 60°±1, with a limit angle of 180°± 1. Service life exceeds 60000 cycles without load.
