Motenergy ME0810 DC Permanent Magnet Motor – Similar to ME0708 but with Shorter Shaft

Description

Features include:

This is the same motor as the ME0708 but has a temp sensor and a shorter shaft. All units have been upgraded to the newest high tempature bush sets. This ME0810 is a Brush-Type, Permanent Magnet DC motor with very high efficiency. Capable of 4.8 KW continuous and 15 KW for 1 minute. For voltages from 12 to 48 VDC input and 100 amps continuous (300 amps for 1 minute). This is the motor used by Zero Motorcycles in their 2010 48 volt applications.

Power	4.8 KW continuous and 15 KW for 1 minute
Voltage	24-48 Volts
Speed	3360 rpm at 48V Unloaded
Size	8″ OD, 5.9″ long (w/o shaft)
Shaft	7/8″ x 3/4″, 3/16″ key
Weight	28 lbs.

We recommend that you use an SR48400 that is turned down to 75% power output. Because the ME0810 has such a low inductance, the controller sees the motor as if it was a short circuit. By having this large controller, it can withstand this low inductance. It is also required to use a contactor that is rated for 200 amp continuous like the MZJ-200D with the appropriate diode & pre-charge resistor.
