Get motors spinning in minutes with InstaSPIN

Texas Instruments InstaSPIN is an advanced sensorless motor control technology that can automatically identify motor parameters and enable designers, even those with limited motor control experience, to implement sensorless motor control for any type of synchronous or asynchronous 3-phase motors.

InstaSPIN is now fully supported in PSIM, both in terms of simulation and hardware implementation. Using the InstaSPIN technology, PSIM provides the complete and easy-to-use solution to the design and implementation of high-performance sensorless motor drive, from motor parameter identification to current/speed controller design and hardware implementation. With this capability, PSIM provides the easiest way for users to evaluate the performance of a motor control algorithm with InstaSPIN.

The heart of InstaSPIN is the  FAST algorithm which runs in the ROM memory of InstaSPIN-enabled MCUs. InstaSPIN requires a long list of parameters that are not so easy to understand and define, and the InstaSPIN code structure is complex. This has made it difficult for designers to evaluate InstaSPIN and integrate InstaSPIN into their product development easily.

PSIM is the first package that fully supports InstaSPIN, from parameter file creation to controller design, simulation, and auto code generation. You can use PSIM’s InstaSPIN Parameter Editor to prepare the parameters needed for InstaSPIN based on system hardware and operating conditions. Then use PSIM’s Motor Control Design Suite to design for the current loop and speed loop PI controllers easily, and simulate the complete system with the power stage and control (including the InstaSPIN block) to validate the design and the performance of the overall system. After simulation, you can make use of PSIM’s easy-to-use automated code generation capability to generate code for InstaSPIN-enabled DSP hardware.

Detailed step-by-step instructions are given in tutorials listed below, describing how to go through the entire process to design and implement a PMSM sensorless motor drive.

FAST Block Estimator

The core of the InstaSPIN algorithm is the FAST estimator that performs parameter identification and calculation of flux, angle, speed, and torque based on motor phase voltages and currents and dc bus voltage.
