Integrated Motor-Differential Drive System

Are you looking for a cost-effective drive system which will allow your vehicle to climb hills faster? Are you thinking of converting your golf car to a powerful, high-speed, off-road hunting buggy? Look no further, here's your solution!

Hot rod your ATV, UTV, Golf Car or NEV (Neighborhood Electric Vehicle) with the latest brushless PMAC pre-wired and tested drive system from Electric Motorsport. This new, lightweight, high efficiency system includes a 9.91:1 or 15.7:1 differential to facilitate conversion of gas engine vehicles or replacing old worn out transaxles. It can also aid in the conversion to taller tires (depending on the original ratio) Solar cars and robotics projects can also benefit from a system featuring integrated differential and the hassle-free compactness of integrated motor and transmission.

Differential -

Differential gearbox with two-stage reduction and parallel axes, expressly designed by COMEX for light vehicle applications, such as micro-cars and small working vehicles powered with an electric motor. The use of external carters in aluminum alloy and gears in alloyed steel with surface hardening ensures lower weight and the highest durability. Moreover the teeth of the gears are super-finished (power Honing), the only product on the market with this kind of mechanical operation, to optimize efficiency and reduce noise during operation under load.

Differential Specifications:

Gearbox typology: two-stage with parallel axes 
Two available ratios: 9.91:1 and 15,7:1 
Max output torque: 1000 Nm 
Max electric engine RPM: 7000 RPM 
Single speed Efficiency: 96% 
Installation tilt (X): from 0° to 180° 
Built-in sensor for electronic odometer 
Suggested oil type: Gear box oil SAE 80W90 
Suggested oil quantity: 0.8 liters 
Dry weight: 11.3 Kg 
Gears super-finishing (Power Honing)

Controller -

 The Gen4-series represents 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
