New tool set from Motorola simplifies development of AC motor drives.

PHOENIX--(BUSINESS WIRE)--May 13, 1997--Motorola Semiconductor Products Sector Tuesday announced the introduction of a set of board level products aimed at the variable speed motor drives market.

The two-piece tool set consists of a digital motion control board featuring the MC68HC708MP16 8-bit microcontroller (MCU) and an IGBT power stage board. The power stage is designed to drive 3 phase motors up to 1 hp from DC bus voltages up to 380 volts.

The digital motion control board, ITC137, provides the user all of the basic motor control functions with "on/off" and "forward/reverse" switches and a "speed control" potentiometer. A serial port is also available for changing motor control parameters real time from a PC.

The included 64 pin, 8MHz, MC68HC708MP16 MCU incorporates two timer interface modules (4ch & 2ch) with input capture, output compare, an 8-bit, 10 channel A/D converter, and a 6 channel, 12-bit pulse width modulator (PWM) featuring programmable frequency & polarity, center or edge alignment, dead-time generation & compensation, distortion correction, hardware fault pins and 20 mA sink capability. Also included are SCI, SPI, low voltage reset, crystal or ceramic resonator and 37 bi-directional I/O lines.

Packaged as a complete kit (KITITC137/D), the digital motion control board comes coded with a basic "turn a motor" program which is also supplied on an accompanying diskette. A user's application note and two ribbon cables for connection to the power stage (drive & feedback signals) are also included.

Terminals are provided on the board to accommodate hall sensor system connections. The digital motion control board is designed to run on its own or, with the MCU removed, it will connect to the M68EM08MC16 emulation module with an M68CBL08A cable and an M68TA08MP16P64 target head adapter. For purposes of motion control code development, the emulator may be run on either an MMDS08 or MMEVS08 development board.

The high voltage power stage board, ITC32, is designed to provide a direct interface between microcomputer based controllers, such as the ITC137, and brush DC, brushless DC and AC induction motors.

It accepts six logic inputs which control three IGBT Half-Bridge outputs featuring Motorola's new MHPM6B15A60D VersaPower(TM) Hybrid Power Module, MC33153D high voltage IGBT Gate Driver and the HCPL0453 optoisolator. In addition to controlling the motor, the board provides current sense, temperature sense and bus voltage feedback terminals. The complete kit (KITITC132/D) includes a user's application note.

The two development boards can work independently or be coupled together to form a tool set. As a coupled tool set, they require only power supplies and a motor to create a functional motor drive system.

When connected to the software development tools as described above, code development can be performed without the necessity of building hardware and the effects of code modifications can be observed real time. This tool set permits rapid microcontroller based system design and development with minimum effort. It is equally well conducive to the learning experience in University Laboratories.

Pricing for the 68HC708MP16 motion control development board kit (KITITC137/D) is $375.00 each. The high voltage power stage development board kit (KITITC132/D) is also priced at $375 each. Pricing is in U.S. dollars for U.S. delivery only. Both kits can be immediately ordered from stock.
