Input power supply 4.5V to 5.5V DC, the project can drive load up to 1A for each channel. Connector CN1 is provided to program the ATMEGA328 chips using Arduino IDE.

Intelligent Power Module (IPM) board has been designed using FSBS5CH60 IC from Fairchild, which provides a fully-featured, high-performance inverter output stage for AC Induction, BLDC, and PMSM motors. These modules integrate optimized gate drive of the built-in IGBTs to minimize EMI and losses, while also providing multiple on-module protection features including under-voltage lockouts, over-current shutdown, and fault reporting. The built-in, high-speed HVIC requires only a single supply voltage and translates the incoming logic-level gate inputs to the high-voltage, high-current drive signals required to properly drive the module’s internal IGBTs. Separate negative IGBT terminals are connected to the shunt resistor to provide the current feedback to the micro-controller. This IPM module helps to develop lots of power applications and also can be used as H-Bridge for brushed DC motor. The module mainly helps to drive Hall sensor-based or encoder-based motors, it doesn’t support the FOC algorithm, FOC-based IPM board is under development and will be published soon.

The project presented here is a 3-phase Brushless motor driver. The project consists of an L6235 device which is DMOS fully integrated 3-phase motor driver with overcurrent protection. Manufactured in BCD technology, the device combines isolated DMOS power transistors with CMOS and bipolar circuits on the same chip. The device includes all the circuitry needed to drive a 3-phase BLDC motor including a 3-phase DMOS bridge, a constant off-time PWM current controller, and the decoding logic for single-ended hall sensors that generates the required sequence for the power stage. Running the project in stand-alone mode, instead, three control pins enable the device, setting the direction of the rotation, breaking the motor, and the jumper chooses to run in torque or speed mode. The board is suitable for small motors used in many home appliances and can handle torque and speed control with a high efficiency of up to 95%.

This is a Smart power module project designed for Small Power AC Motors. The FNB40560 chip is the heart of the project. A compact inverter project is ideal for small power motors such as fans and pumps. H-bridge configuration can also be created for low current high-voltage brushed DC motors. The Inverter project supports loads up to 5A. The DC power supply voltage is up to 400V_DC. The project operates with 6 PWM signals. The parameters for bootstrap circuit elements are dependent on the PWM algorithm. For 5 kHz of switching frequency Bootstrap capacitors C2, C6, and C8 value is 33uF. Resistor R4, R5, R6, R12, R11, R8 and capacitor C9, C10, C11, C15, C16, C17 prevent improper signal due to surge-noise. ATS pin is provided to monitor the temperature of the IPM. A heatsink is needed for the IPM chip during operation or testing.

The project presented here is a three-phase sinewave PWM driver for high-voltage brushless motors. The board is built using TB67B000AHG chip, which is a high-voltage IC capable of handling 600V. The TB67B000AHG has a 2-in-1 (MCP) structure of controller (sine-wave PWM / wide-angle conduction) and a high-voltage driver. The rotation speed of a DC brushless motor can be controlled directly by the speed control signal (analog voltage) by an onboard trimmer potentiometer or from a microcontroller. The board supports a 3-phase BLDC motor with Hall sensors. On Board Trimmer, the potentiometer helps users to control the speed of the brushless motor.

This BLDC motor driver board is equipped with a smart IFX007T half-bridge. The BLDC motor control project is capable to drive one BLDC motor. Alternatively, it can be used to drive one or two bi-directional DC motors (H-Bridge configuration, cascaded to support the second motor) or up to three uni-directional DC motors (half-bridge configuration). The implemented integrated IFX007T half-bridges can be controlled by a PWM via the IN Pin. Interfacing to a microcontroller or Arduino is easy by the integrated driver IC which features logic level inputs, diagnosis with current sense, slew rate adjustment, and dead time generation, etc. The three IFX007T half-bridges are also fully protected against over-temperature, under-voltage, overcurrent, and short circuit events. The project is capable of high-frequency PWM e.g., 30Khz. All inputs are logic level, current sense outputs are for diagnosis purposes, and slew rates are adjustable using R7, R8, R9. This is able to be used for fast and inexpensive prototyping of (BL)DC motor control, easy testing of half-and full-bridge motor control Status flag diagnosis with current sense capability, Over-temperature shut down with latch behavior and under-voltage shut down. It is advisable to use forced cool air to control the temperature of the IFX007 chip.

This is an advanced Motion module providing a fully featured, high-performance inverter output stage for AC induction, BLDC and PMSM motors such as refrigerators, fans, and pumps. This module is based on NFA50460 chip which integrates the optimized gate drive of the built−in IGBTs (FS4 RC IGBT technology) to minimize EMI and losses, while also providing multiple on−module protection features including under−voltage lockouts and thermal monitoring. The built−in high-speed Driver IC requires only a single supply voltage and translates the incoming logic−level gate inputs to the high voltage, high current drive signals required to properly drive the module’s internal IGBTs. Separate open emitter IGBT terminals are available for each phase to support the widest variety of control algorithms. Heatsink is a must for the IC before conducting any test.

Driving a 3-phase brushless DC motor is very easy with this product. It is a simple and easy-to-build project that requires only a few external components. The circuit is based on AMT49400 IC which is an advanced 3-phase, Sensorless, brushless DC (BLDC) motor driver with integrated power MOSFETs. The chip includes the field-oriented control (FOC) algorithm which is fully integrated to achieve the best efficiency and acoustic noise performance. The motor speed is controlled by applying a duty cycle signal to the PWM input. Users may use Arduino, microcontroller, or discrete circuit to generate PWM for the speed controller. It is a hassle-free easy to use board, just connect the 3 phase brushless motor, connect the power supply and feed PWM to control the speed of the motor. This project is the best choice to drive a FAN motor, small pumps, and brushless toy motors, etc. The circuit also outputs FG speed output information which can be used for feedback. Chip also has a short circuit protection feature that prevents damage to the IC or motor. Any of these three conditions: phase to GND, phase to VBB, and phase to phase will trigger the OCP event, and the AMT49400 will stop supplying current to the motor immediately. The OCP can recover after a power cycle or PWM demand cycle. If the OCP restart mode (EEPROM setting) is “time”, the OCP can recover after 5 seconds.

This is a 3-Phase Inverter Driver project designed for Low Power AC Motor. The FSB50450AS chip is the heart of the project. A compact inverter project is ideal for small power motors such as fans and pumps. An H-bridge configuration can also be created for low-current high-voltage brushed DC motors. The Inverter project supports loads up to 1.5A. The DC power supply voltage is up to 400V DC. The project operates with 6 x PWM signals. Parameters for bootstrap circuit elements are dependent on the PWM algorithm. For 15 kHz switching frequency, Bootstrap capacitors C1, C2, and C3 value is 1uF. Resistor R1, R2, R3, R4, R6, R7 and capacitor C4, C5, C6, C7, C8, C9 prevent improper signal due to surge-noise. Over-current or fault detection circuit is created using comparator CN5 – LMV7239 and shunt resistor R5. The output of LMV7239 is normally high and goes low when an over-current condition occurs.
