The fastest rectifiers in the west
The MUR range of ultrafast rectifiers from Solid State Supplies have been specifically designed to provide optimised performance of forward voltage drop with a reverse recovery time of 25ns.
Ferroelectric RAM handles repeated rewrites
The FM24C04 4Kbit FRAM serial memory from Solid State Supplies is ideal for nonvolatile memory applications which require frequent or rapid writing.
Using one of two control algorithms - Hall-effect sensor feedback trapezoidal drive and sensorless extended Kalman estimator (EKE) sinusoidal drive - the SOM9300 also features direction control, cycle-by-cycle current limit, torque control for fast response to electrical disturbance and velocity output feedback.
The control and interface board with DSP, voltage and current sensor and an isolated RS232 interface and and integrated power module are fitted to a standard heatsink and then connected to the motor.
The control board uses an ADMC331 single chip motor DSP and the power module houses a three-phase PWM inverter and high/low side drivers.
Supplied with all connections and software, the SOM9300 requires a 28V/5A supply, a power supply for RS232 (isolated +5V logic) and a PC with Windows 95/98, a CD ROM drive, 3.5in floppy drive and an RS232 COM port.
