	BRUSHLESS DC MOTORS: BLDC Series

Compact Size Brushless DC Motor

The Hurst line of BLDC motors have all the desirable qualities of brushless motors in a very small package. Ball bearing construction assures long life.

These motors are also available with an encoder and/or a gear box. They are shown on these data sheets.

Five Sizes of Brushless DC Motors

Continuous torque ratings of the five BLDC Series motors shown in thistable range for 15 to 500 oz-in. The largest motor (5.36" L) has a peak torque rating of 250 oz-in. The gearhead motor has a peak torque of 500 oz-in. They may be applied whever brush servo motors are presently used and have proven cost effective in many applications. Ball bearing construction assures long life.

Hurst engineers can supply helpful application information and, on request, will recommend economical control systems.

Encoders are specifed by changing the suffix from -003 to -004.
