Bodine Electric Company has introduced a digital pulse width modulation (PWM) controlled version of its INTEGRAmotor line of standard products. The motors combine the four elements of a typical motion control system -- a control, a brushless dc motor, a gearhead, and an optical encoder. The design is said to reduce wiring problems, assembly time and cost, as well as minimize EMI.

The PWM models combine a 24 Vdc brushless dc motor with a built-in open loop voltage mode PWM controller. PWM controls digitally encode analog signal levels by using high-resolution counters. Bodine controls used in the type 22B/FV or 34B/FV INTEGRAmotors accept PWM input from an external motion controller or PLC. Units feature amplifier enable, direction input, dynamic braking and a built-in 256 ppr and a 2-channel encoder.
