Motor Control Technologies

Toshiba offers microcontrollers that incorporate a digital RDC, a Vector Engine (VE) and one-shot pulse generator. These features help simplify and improve the efficiency of software operations.

* Resolver-to-Digital Converter: a circuit that converts angular (sine and cosine) information from sensors that reside on the motor into digital signals.

Digital RDC integrated into an MCU

Toshiba's microcontrollers integrate an RDC that has traditionally been implemented as a separate chip. This reduces the external part count, saves board space and eases the part approval process. Additionally, the digitalized RDC provides improved noise immunity and greater design flexibility.

The Advanced Programmable Motor Driver (A-PMD) can control up to two motors at low to high speeds and reduces the CPU workload.

Vector Engine (VE)

Toshiba's latest Vector Engine (VE) offers three times the performance of its predecessor due to the increased operating frequency and new features to keep pace with future generations of power devices.

Gen-1 Vector Engine
(TMPM370 (General-Purpose))		 Enhanced Variant of Gen-1 Vector Engine
(TMPM354, TMPR454)		 Gen-2 Vector Engine
(Next Generation)
Features (enhancements) Fixed tasks and schedules Programmable tasks and schedules Trigonometric functions and table lookup
Operating frequency 80 MHz 80 MHz 200 MHz
Enhancements － Greater flexibility Greater flexibility and increased performance (tripled)
One-shot pulse generator

At high RPMs, the one-shot pulse generator allows the A-PMD to control motors with one pulse per revolution, thereby making it possible to spin them at 15,000 RPM or faster. At mid to high RPMs, the one-shot pulse generator results in an approximately 10% increase in the motor output power, compared to asynchronous PWM control. This provides greater flexibility in the use of smaller batteries or motors.
