MCUS offer ‘breakthrough’ performance for motor control applications
1 min read
A new series of 16bit PIC microcontrollers and dsPIC digital signal controllers (dsc's) has been introduced by Microchip.
According to the company, the devices bring advanced control and 'breakthrough' performance to cost sensitive general purpose and motor control designs. They are designed to enable low cost, sensorless motor control designs and include support for a range of motor control algorithms.
Other features include an on-chip charge time measurement unit, 10bit a/d converter and mTouch capacitive touch sensing. The devices are supported by three new plug-in modules and a single board motor control starter kit. This includes capacitive touch sliders and an onboard brushless dc motor. Microchip claims the starter kit makes it easy for designers to create high performance appliances, such as washing machines, medical products such as infusion pumps and industrial ac induction motors.
The dsPIC33FJ16, dsPIC33FJ16 and PIC24FJ16 devices are optimised for general purpose and motor control applications. The dsPIC33FJ16 dsc's include an on-chip ctmu, a/d converter peripherals, a real time clock/calendar and up to 21 general purpose output pins. They are targeted at driving intelligent sensors.
The dsPIC33FJ16 and PIC24FJ16 devices include a 6 channel pwm peripheral with synchronised outputs for three phase operation, enabling support for a range of motor control algorithms and applications. These range from simple sensored motors to advanced sinusoidal field oriented control, brushless dc, permanent magnet and synchronous as induction motors.
