A Fully Hardware-Implemented PMSM Motion Controller IC Solution
Malaysia’s national R&D agency in Information and Communication Technology, MIMOS,
together with two local R&D companies has developed the MCGP02I series to efficiently
control and manage the performance of Permanent Magnet Synchronous Motors (PMSM).
A PMSM is a rotating electric machine which uses permanent magnets in its rotor whereby
an alternating current flow in its stator windings would generate a rotating magnetic field to
cause the rotor to rotate. PMSM motors can be found in consumer appliances such as airconditioners, washing machines, printers and commercial products such as lifts, elevators
and conveyor belts.
While traditional solutions for controlling the PMSM motor use software written for a
microcontroller or microprocessor, MIMOS’ MCGP02I motion controller solution uses a new
design approach in which complex mathematical calculations required for Field Oriented
Control (FOC) of PMSM motors are directly implemented using specialized logic gates into
an IC.
The FOC method is the most efficient control method to squeeze maximum performance
out of the PMSM motor. This method produces reduced torque ripple resulting in smoother
motor performance and quieter operation. There is also no need to write firmware to
implement the complex FOC algorithm, thus total development cost of the system is greatly
reduced. The programmability of all control parameters enables maximum flexibility and
quick design of control systems.
The MCGP02I comes in a 40-pin small footprint QFN package with an integrated on-chip
oscillator, ADCs, voltage references and regulator. With the MCGP02I, the complete control
system can be constructed with minimal number of components and occupies a small PCB
area. The MCGP02I is compact, economical and can be implemented without the need for
complicated firmware or assembly code.
This solution is expected to increase the application of PMSM motor development,
especially for Small and Medium Enterprises. With PMSM motors being used in a variety of
applications, business opportunities for this solution are tremendous.
