BPW-S1 The BPW-S1 is a high power brushless PWM servo amplifier in an 8E size Edge Mount format. It is ideally suited to torque control applications or for velocity control using a digital position controller. This amplifier can be configured for External Sinusoidal commutation or for self commutation using Digital Hall effect sensors.

When using external sinusoidal commutation, the amplifier receives two 120° out of phase sinusoidal command inputs. The optimal third phase is derived by the amplifier. This eliminates "cogging" and greatly enhances low speed operation. An optional backplane is available to allow quick and easy access to motor, power, control and other I/O signals.
