SENSORLESS BLDC MOTOR
DIGITAL SPEED CONTROLLER
The Digital Vector Motor Drive is a digital motor controller
designed for high reliability and industrial motor control
applications. This controller utilizes space vector modulation
control design for maximum utilization of the DC bus voltage
and provides smooth torque control. The DC bus voltage
operating range is 100V to 800V. The flexibility of this design
allows use of a single device/part number for multiple motor
applications with few hardware changes. There are two internal
assemblies in a small footprint module: the Field Oriented
Control (FOC) hardware and a 3-Phase Bridge. The FOC
hardware is programmable via an isolated RS-232 input port,
and the 3 Phase Bridge designs are rated up to 40A,1000V
utililizing IGBT’s or 60A, 150V with MOSFETs. The sensorless
algorithm allows start up to be tuned for almost any load.

BLOCK DIAGRAM
The vector drive is programmed via an Isolated RS232 Interface to configure the motor and control
parameters. The FOC Hardware has an inner torque loop (Sinusoidal/Space Vector/FOC -Field Oriented
Control) and an outer speed loop. The torque loop uses a digitally tunable P+I controller and integrated
phase current sensors. The speed loop uses a digitally tunable P+I controller and speed feedback derived
from the FOC. Sensorless startup is performed open loop using a Volts-per-Hertz algorithm. The Volts-perHertz startup parameters are digitally configurable. Space vector modulation allows for the motor line to line
voltage to reach the full DC Bus Voltage without waveform clipping unlike other sinusoidal control methods.
SOFTWARE
The device is configured using a windows based Configuration Utility. The Utility configures the motor
parameters through the RS232 interface. It also is designed to control/run a motor directly while monitoring
information such as speed, current and voltage. This software enables the controller to operate a motor with
improving engineering development time on motor control applications.
