The controller is non-input/output isolated, meaning that the grounds between the digital input and the motor control output are common. It is constructed in a convenient electrically isolated hermetic package. The controller is capable of 10 amps continuous output current with 55V absolute maximum rated voltage MOSFETs, allowing 38V of maximum motor supply voltage. Bridge protection features, such as shoot-through and cross conduction protection are provided by the gate driver circuitry. The digital signal processor controls torque or speed with Field Oriented Control (FOC) and Space Vector Modulation output to the motor windings. The processor uses an incremental encoder with index input from the motor output shaft to track mechanical shaft angle. The FOC algorithm uses current measurements from internal sense resistors to perform closed loop torque control, where torque is proportional to current. It can also operate in closed loop speed control mode, using the encoder as a speed feedback element in combination with a torque loop. All control is accomplished using CAN bus for all communication for command, control and parametric information input. This eliminates the need for D-A and A-D conversion from the host controller. Current / speed commands, monitoring and all parametric set up values are input using CAN. Parametric set up values and CAN addressing are all stored in on-board EEPROM. The MSK 4367 has good thermal conductivity for MOSFET output stage power dissipation due to the electrically floating and isolated package design that allows direct heatsinking without insulators. AN031 1 The evaluation board provides a platform from which to evaluate new designs with ample real estate to make changes and evaluate results. Evaluation early in the design phase reduces the likelihood of excess ripple, instability, or other issues, from becoming a problem at the application PCB level. This application note is intended to be used in conjunction with the MSK4367 data sheet. Reference the device data sheet for additional application information and specifications. Setup Use the standard 4mm banana jacks to interface with the assembly to connect to your power supply and motor assembly.
