In Stock MTSPF7.5R 75V 50A Round VESC based on VESC75/300 for for Ebike Conversion Esk8 Robotics

• Overview： 

MTSPF7.5R is a circular PCB ESC based on 75V VESCTOOL software and hardware structure. It is mainly used for brushless motors on mobile devices with battery voltages below 18S Lipo. And the round size is particularly suitable for combined installation with large joint motors, to be used for position control of robotic arms and robotic dog legs, etc. In addition, it can also combine with an underwater motor for underwater propulsion and used for electric skateboard, cable camera, electric bike, etc.

• PCB layout, size and heat dissipationIt adopts a double-sided 6-layer board layout and a separate design for strong and weak electricity. The production process is 6x3oz immersion gold. Increase the MOS copper area to facilitate heat dissipation, and at the same time by adding via holes to conduct heat, the heat is transferred from the metal bottom surface of the MOS to the back surface of the PCB and to the heat sink. Compared with the traditional heat dissipation from MOS resin surface, the thermal resistance is lower and it’s conducive to work in confined spaces.
• MOSFET: American Fairchild FDBL0150N80 ( Fairchild, which has been acquired by ON Semiconductor).
• Driver IC: American TI company UCC27211. This chip is also used on MTSPF7.5H 300A 85V Controller On MTSPF7.5H, the driver IC drives four parallel MOS without any pressure; while on 7.5R, it only drives one, which is even more fearless.
• Current High-Speed Sampling Chip: American TI Company INA240. It can make the current sampling faster and more accurate, and has a good improvement on the FOC and over-current protection functions.
• DC-DC module: The first stage DC-DC uses TI's LM5161 to convert the main power supply voltage to 12V; The second level of DC-DC uses Microchip's MCP16311 to convert 12V to 3.3V and 5V. The current of the two-stage voltage conversion chip is 1A. Considering that the internal circuit needs 100ma, the external output current is controlled within 900ma.
• CANBUS interface chip: TJA1051 of NXP Company.
• Capacitor: 4pcs Japanese Rubycon ZLH 80V 330uf.
• Encoder: This ESC does not integrate the AS5047 encoder chip. If necessary, please purchase the encoder board separately.
• Firmware standard: VESCTOOL automatically recognizes this ESC as 75_300. This firmware can be used.
