Have a read around here in regards to what brands are recommended, especially if you’re concerned about after sales service. These benefits come at the cost of potentially less rugged, more complex, and more expensive control electronics.

I did some testing yesterday to check the voltage sag on my battery under different conditions, and from a 58v charge, with the full throttle at stop I saw the voltage sag briefly to just under 53v (surprised me), so I'm guessing it's pulling more than 40 amps from the battery at that point (52v 20 Ah pack with cheap Chinese cells). A Wye-connected winding does not contain a closed loop in which parasitic currents can flow, preventing such losses. Feedback: Your satisfaction and positive feedback is very important for us, if you have any problems, don't hesitate to contact us. I am interested in 24 36V 800W DC Motor Controller By Lithium Battery 48V 1000W could you send me more details such as type, size, quantity, material, etc. The controller performs similar timed power distribution by using a solid-state circuit rather than the commutator system.And, nobody likes to bring this up, but your weight can be all the problem, if you are over 200 pounds. An electronic controller replaces the commutator assembly of the brushed DC motor, which continually switches the phase to the windings to keep the motor turning. I do need to alter the low voltage protection circuit in the controller though, as it won`t run because it thinks the voltage from the 36v is too run down from the expected 48v. Volt Controller And Throttle Ebike The Drive Motor Starts More Smoothly And Makes Riding More Comfortable. They also contain toxic metals, 4-7 times less energy by the same weight, and have a memory effect problem.

For the record my controller of 15 amps 30 amps max has what I would consider a good amount of power even though I neutered it to max at 1000 watts. Reading the forum, I understand that the motor should work ok with 36volts, giving out a max power of about 750w, and would actually be under less stress than it`s specified 48v construction. Anyhow, now that we don't throw as many parties anymore since we've become serious the extra fridge in the garage is good for something again. This is sensored controller , so controller has three big cables and five sensor wires and one speed sensor wire.The higher capacity controller may help with toasting your controllers, but may not get rid of the of the problem, if the battery is the root cause of the failures. Your battery is probably hitting it's low voltage cutoff, which can happen even if it's not "empty", if you're drawing far more current than it's rated to provide.

or 36V Universal (support both voltage) Support LED Control Panel or LCD Control Panel or without any Control Panel (Universal) Support24V or 36V Light Control Rated current: 8A Maximum Current: 17A It only applies to hub motors with Hall sensors. As the rotor rotates, the commutator selects different windings and the directional current is applied to a given winding such that the rotor's magnetic field remains misaligned with the stator and creates a torque in one direction. This control system is an alternative to the mechanical commutator (brushes) used in many conventional electric motors.

Other sensorless controllers are capable of measuring winding saturation caused by the position of the magnets to infer the rotor position. or 36V Universal (support both voltage) Support LED Control Panel or LCD Control Panel or without any Control Panel (Universal) Support24V or 36V Light Control Rated current: 10A Maximum Current: 20A It only applies to hub motors with Hall sensors.
