DDS Elettronica - Motor Control

Electronic motor Control DDS Elettronica has many years of experience in the field of designing electronic motor controls. We have previously designed and developed many control circuits which are applicable to a wide range of systems. However, as always, if you have a specific application whose requirements are not fulfilled by our previous designs, we will develop tailored circuits on demand.
	3 Phase Induction Motor Control We have previously designed and created the DDS062, a tri-phase STATIC contactor / inverter. It replaces a standard mechanical contactor with an electronic 'static' equivalent. Since it has no moving parts to wear out, it has a theoretically infinite lifespan.
This circuit can activate the motor in two directions- forward and reverse. As it is a digital method of control, the motor is at full power in either direction, or off. It has built-in safety time delays to avoid damage to the motor when it is switched quickly from forward to reverse and vice-versa. We are also in the process of developing an analogue (V/f) tri-phase inverter, which will allow a more complete control of the motor.
	Brushless Motors To-date, we have developed a square wave brushless DC motor control with a maximum current and voltage of 1.5A and 500V respectively. We are in the process of developing a sensorless sinewave controller for brushless DC motors where the digital section is DSP based, and the power section can supply a max current and voltage of 2A and 60V, although this maximum will be expandable by simply changing the power section.
These products are all microprocessor based, and the digital control section also includes: - Digital Input (commonly used to connect the zero position sensors) - Incremental Encoder - Serial RS485 or DMX port - EEPROM to store setup details - A fault-indicating LED - DIP switch to select the controller address
	Stepper Motor We have developed various types of microstepping circuit, for 3, 5 or 12 axis of movement. They will work for motors up to a maximum of 700mA/1.5A and 45v.
These circuits all use: - Digital Input (commonly used to connect the zero position sensors) - Serial RS485 or DMX port. - DIP switch for address selection. We have also developed a single axis microstepping circuit, capable of taking motors up to 14A, 70V. These come with: - Digital Input (commonly used to connect the zero position sensors) - Serial RS485 and DMX. - DIP switch for address selection. - Input for incremental encoder.
	DDS65 This is our standard circuit mount, for mono and triphase circuits, stepper motor control boards, and for use with any commercial actuator in Eurocard circuit format. These mounts are useable with triphase/ monophase systems up to a maximum of 145V (AC).
