Motor driver with integrated controller D30/5/4QF-E2

Product catalog summary

Overview: The D30/5/4QF-E2 is a compact digital controller designed for managing brushless motors up to 150 W without the need for hall sensors. It features a 4-quadrant operation, allowing for precise control of motor speed and direction.

Key Features:

Operates as a closed-loop speed controller with a maximum speed of 60,000 rpm for motors with 2 poles.
Accepts set value inputs via external analogue voltage (0 to +3.3 V) or PWM at 200 Hz.
Includes SCI protocol and FOC with closed-loop torque regulation.
Direction of rotation can be preset using a digital signal.
Output stage can be enabled or disabled, with motor speed monitoring via 'FG' output and status indication via 'Ready' output.
Features motor blocked protection with a current limit for blocked motors.

Output Specifications:

Drive output to one brushless motor at 0.95 * supply voltage VCC.
Speed output is 20 times the output frequency.
Operation current is 5 A, with a peak phase current limit default at 10 A.
PWM frequency is set at 20 kHz.

Input Specifications:

Power supply input ranges from 12 to 30 VDC with less than 5% ripple.
Control inputs include analogue speed command (0 - 3.3 VDC), PWM speed command (200 Hz), and current command (0 - 2 VDC).
Enable and direction signals are at +3.3 VDC, with four digital inputs also at +3.3 VDC.

Operating Mode:

Functions as a closed-loop speed and current controller.
Includes current limiting to safely operate beyond preset current limits.

General Specifications:

Utilizes an STM32F103C8T6 microprocessor with 95% efficiency.
Mounting is plug-in with female headers RM 2.54 mm and RM 2.0 mm.
Dimensions are 48 x 35 x 12.7 mm, and it weighs 12 g.
