Got the frame from a motorcycle salvage yard. If anyone recognizes what kind it is, please let me know.
MotorJX Motor Co., LTD MY1070 Permanent Magnet DC
750W (1HP), 2500RPM, 36V, 27A.
Inconsistent since 36 x 27 = 972.
However, the motor will only draw a certain amount of current at 36V depending on the resistance of the windings.
Controller CT-660B9
36V, 40A but having serious problems with reliability. Failure mode is "on" making for dangerous riding. Need a kill switch. Have alerted BBB, NSC, CPSC, and NTSB. Also plan to incorporate a turbo relay and design a reliable, repairable controller.
Batteries3 Werker SLI24MDP, 12.00 Volt, Lead-Acid, Flooded
Marine Dual Purpose Starting and Deep Cycle Battery - 31Ah but that's not what I'll get out of it since the Ah rating is based on a trickle discharge and I can't get specs on this battery for a 20-30A continuous draw. My guess is about 20Ah but then they recommend not going below 50% to increase battery life so that brings it down to about 10Ah. Have since moved to three WKA12-9F2 batteries. Better for mounting and space constraints.
System Voltage36 Volts
Charger HG6S360160
Manuf not printed on box for some reason. Has worked well charging thru the controller except most recent when controller worked before charging then didn't work after charging.
Top Speed20 MPH (32 KPH)
11 tooth front sprocket
55 tooth rear sprocket
AccelerationExcellent! Climbs hills very well except the steepest mountain roads at the end of a 5 mile trip.
Range5 Miles ( 8 Kilometers)
Based on battery assumptions above. I haven't seen an honest description of range in any retail advertisements. Three WKA12-9F2 give about 5 mile range (10 mile round trip) or 10 miles out then recharge for return.
