40hp Electric Drive System 72-80V 350A For Marine or EV
Bought this setup for a project and didn't use. Brand new, inbox kit.
PMAC Drive Kit
The Electric Motorsport PMAC-DS kit will convert your gas or diesel engine to clean, silent electric propulsion! This kit is designed for inboard or outboard electric marine drive system conversions (specifically sailboats or light boats), but is also suitable for many other applications. Electric drive systems of this power usually cost $7,500 and up, but this *pre-assembled kit makes it affordable at less than half of the cost.
Features
Variable Throttle for smooth speed control
Brushless Motor design makes brush maintenance a thing of the past.
Easy forward and reverse switching with a flip of a switch
Motor and Controller support Regen which means with an appropriate prop this system can recapture energy to help recharge the battery pack. So under a heavy sail this system can be generating power off the dragging prop*.
Drive motor can be mounted inboard OR outboard.
*Pre-assembled and tested releiving you of any guesswork.
Kit Includes
Mars Brushless PMAC DS motor
Gen4 Controller
Twist Throttle
Foreward/Reverse switch
Ignition key
Contactor
Fuse
Wiring harness
Motor Specifications
Brushless Permanent Magnet Motor
4 pole motor (8 magnets).
Power: 12 kW Cont, 30 kW Peak
Phase to Phase winding resistance: 0.013 Ohms
Maximum recommended rotor speed: 5000 RPM
Voltage: 0 to 96 VDC input to the control
Inertia: 45 Kg Cm Squared
Current: 150 Amps AC continuous (180 Amps DC into the motor control)
Peak current: 420 Amps AC for 1 minute (600 Amps DC into the motor control)
Weight: 35 pounds
Peak Stall Torque: 93 Nm.
Cooling: Open Frame, Fan Cooled motor.
Controller Specifications
The Gen4-series represent the absolute latest design concept for compact and reliable AC Controllers. They feature the smallest footprint in the industry for their power capability. The high efficiency of these controller makes it possible to integrate them into very tight spaces without sacrificing performance. The design has been optimized for the lowest possible cost while maintaining superior reliability in the most demanding applications.
The Gen4 controllers are designed to control either AC Asynchronous motors or PMAC Synchronous motors. This feature allows users to select optimal motor solutions for any application. Both UVW and encoder AB inputs are provided for maximum flexibility.
Features:
Sealed IP66 enclosure
Integrated logic circuit (I/O)
Advanced flux vector control
Autocheck - system diagnostics
Sensorless control (depending on application)
CANopen product
Nominal Voltage
72 - 80 VDC
Operating Voltage
39.1-116 VDC
Cont. Current (120s)
140A
Peak Current (120s)
350A
Boost (10s) 420A
Please note: Due to the high RPM of the Mars Brushless motor, we recommend using a gear reduction system rather than direct-drive. This will improve efficiency, provide proper torque and cooling, and prevent cavitation. Typical reduction is around 1.5:1 to 3:1, but will depend on the required propeller RPM needed to reach hull speed. Proper reduction will enable the motor to spin your propeller for the required hull speed. This number can be estimated using the 50 rpm/volt constant (72 volts * 50 rpm/volt ~ 3600 rpm max). *Appropriate prop required based on motor rpm and the boats hull speed.
*** Although this kit is pre-assembled, there are certain tasks that you will need to do prior to use. You will need to connect the motor, check all the nuts, bolts, and screws to make sure they have adquate tightness (8 foot pounds of torque on the terminals) after shipping, and assemble and connect your battery pack.
