Description

BLS3325 180 Degree - 7.4V 0.055sec High Speed Brushless Servo

The BLS3325 180 Degree variant is based on the 7.4V 0.055sec High Speed Brushless Servo configuration. It uses a Brushless motor, double bearing, a 183 gear ratio, and a 300 ± 5 mm connection lead. The mechanical size is 40 x 20 x 38 mm, with a listed weight of 85 g and IP67 waterproof performance.

Its operating-voltage range is 4.8-8.4V. Electrical performance is specified as follows: 4.8V: 0.08 sec/60° speed, 18 kg-cm stall torque, 3.2 A stall current; 6V: 0.065 sec/60° speed, 22 kg-cm stall torque, 4 A stall current; 7.4V: 0.055 sec/60° speed, 26 kg-cm stall torque, 5.2 A stall current; 8.4V: 0.05 sec/60° speed, 30 kg-cm stall torque, 6.2 A stall current. This listing is prepared for the 180° running-angle version, using PWM control with a 500-2500 µsec pulse-width range, 1500 µsec neutral position, 2 µsec dead band, and 50-330 Hz operating frequency.
