5 Safety Information Regulatory Compliance The CY8CKIT-037 PSoC® 4 Motor Control Evaluation Kit is intended for use as a motor control development platform for hardware or software in a laboratory environment. The board is an open-system design, which does not include a shielded enclosure. Therefore, the board may cause interference with other electrical or electronic devic ...

6 General Safety Instructions ESD Protection ESD can damage boards and associated components. Cypress recommends that the user perform procedures only at an ESD workstation. If an ESD workstation is not available, use appropriate ESD protection by wearing an antistatic wrist strap attached to the chassis ground (any unpainted metal surface) on the board wh ...

7 1. Introduction Thanks for your interest in the CY8CKIT-037 PSoC® 4 Motor Control Evaluation Kit (EVK). This kit enables engineers to evaluate Cypress's PSoC family of devices for motor control applications. Based on this kit, customers can create control solutions for three dominant motor types: permanent magnet synchronous motor (PMSM), stepper, and brushless DC (BLDC). ...

13 3. Kit Overview 3.1 CY8CKIT-037 Evaluation Kit Overview The motor control system can be separated into two parts: the driver board and the controller board. The CY8CKIT-037 Motor Control EVK is the driver board, which contains the DC/DC power circuit, dual H-bridge circuit, motor current and bus voltage sampling and processing circuit, protection circuit, user configurati ...

14 Figure 3-2. Connectors for DC Power Input 3.2.2 Motor Winding Connectors J9 and J10 provide four pins for motor windings, as shown in Figure 3-3. The BLDC and PMSM motors use three pins, while the stepper motor application needs all four pins. Connection details are as follows: For BLDC and PMSM:  Pin 1–1A (A)  Motor winding A – Red  Pin 2–2A ( ...

Hall Sensors Connector 3.2.4 Connectors to CY8CKIT-042 Board Figure 3-5 shows the Arduino-compatible connectors to the CY8CKIT-042 board: J1, J2, J3, and J4. You can plug the EVK board into the CY8CKIT-042 board through these connectors. For schematic details, refer to Connecto ...

16 4. Kit Hardware Schematic Details 4.1 Block Diagram Overview Figure 4-1 illustrates the CY8CKIT-037 hardware block diagram. The major features are as follows:  Input protection circuit  DC/DC switching regulator  MOSFET dual H-bridge and dual H-bridge PWM drivers  Phase current detecting and processing circuit  Hall and back electromagnetic force (BEMF) sen ...

CY8CKIT-037 PSoC® 4 Motor Control Evaluation Kit Guide, Doc. No. 001-92562 Rev.*A 17 4.2 Input Protection Circuit Figure 4-2 shows the input protection circuit that consists of three parts: overcurrent protection by fuse F1 or F2, power supply reverse protection by Schottky diode D2, and input voltage inrush protection by varistor VR1. Notice that there are two parallel fuses: F1 is a PTC resettable fuse, and F2 is the commo ...

CY8CKIT-037 PSoC® 4 Motor Control Evaluation Kit Guide, Doc. No. 001-92562 Rev.*A 18 The +12V output of the regulator provides power to the dual H-bridge driver chips and the PSoC 4 Pioneer Kit. The other circuits and chips on the EVK board also need a power supply in the range of 2.7 V to 5.5 V, which is VDD. But the EVK board does not contain this converter. It gets this power from the controller board through Arduino head ...

CY8CKIT-037 PSoC® 4 Motor Control Evaluation Kit Guide, Doc. No. 001-92562 Rev.*A 19 4.5 Phase Current Detecting and Processing Circuit As Figure 4-5 shows, three sensing resistors, R34, R35 and R36, are inserted into three half-bridges. When the motor is running, the winding current floats through these resistors. So, detecting the voltage on the sensing resistors can get the phase current of the motor windings. Because of ...
