ELECTRO SALES CO., INC.
:   BLDC Series
Three Size Brushless DC Motor

Continuous torque ratings of the three BLDC Series motors shown on this page range from 15 to 35 Oz-in. The largest motor (5.12" L) has a peak torque of 250 Oz-in. Theymay be applied wherever brush servo motors are presently used and have proved cost effective in many applications.
Hurst engineers can supply helpful application information and, on request, will recommend economical control systems. Models with encoders are available .
