Motor driver with integrated controller D30/7.5/4Q-E2 - 1

Rep. for the Americas: Fisaga Technologies LLC Encinitas CA 92024, USA Tel/Fax: +1-760-944-0495 E-mail: sales@boreasa.com, URL: www.boreasa.com General Description The D30/7.5/4Q-E2 is a small 4-quadrant digital controller for the control of brushless Boreasa blowers up to 225W, equipped with digital Hall sensors. This driver is designed to be integrated into the customer's electronic board. It is also compatible with Boreasa D50/5/4Q-M2 evaluation board. Features: • Maximum Voltage and continuous current: 30 V and 7.5 A • Digital speed control - operates as «closed loop» speed controller • Maximum speed 60'000 rpm (motor with 1 pair of poles) • Set value input through PWM or external analogue voltage (0 ... +3.3 V) • 4 different speed ranges selectable • Direction of rotation preset by a digital signal • The output stage can be enabled or disabled • Maximum output current limit adjustable up to 15 A • Motor speed can be monitored with the «Monitor n» output • Status indication via «Ready» output • Motor blocked protection (current limit for blocked motor) • Protective functions: overvoltage and short circuit protection • Standardized connector strip, pitch 2.54 mm and 2 mm • The built-in shunt regulator is designed to limit the supply voltage of the controller. • An analogue input can be used to detect the temperature of the motor Technical Specifications: Input Specifications Power Supply Input - Nominal 12 - 30 VDC power supply range, ripple < 5% Control Inputs Speed command: 0 – 3.3 VDC Current command: 0 - 2 VDC Enable signal: +3.3 VDC Direction signal: +3.3 VDC PWM Frequency and duty cycle: 200 Hz and 10 ~ 90%, or given by customer Position Feedback with Sensor Interfaces to 3 Hall Effect Position Sensors integrated into the motor. Output Specifications Drive Output Outputs to one BLDC motor: 0.95* Supply voltage VCC Shunt regulator output: PNP output, 10 A Speed output: 20 * output frequency Operation current: 7.5 A Operating Mode Basic Operation Default closed loop. Power/Current Limiting Power or current limiting operating mode (user configurable) so the drive can still safely operate when it exceeds preset power/current limits. Default is current limiting (15 A). General Specifications Microprocessor Contact Boreasa
