SMD 45A User manual

SMD SENSORLESS BRUSHLESS SPEED CONTROLLER AND MOTOR COMBO USER MANUAL.
***Read the data sheet for 3S compatibility***
This is Electronic Speed Controller and motor combo is designed for use in an RC car.
Used incorrectly this system could cause damage or harm so please read this manual
carefully. No liability shall be assumed nor accepted for any damages, losses or costs
resulting from the miss use or poor installation of this product.
Features.
1. Splash proof and dust-proof for all-weather (Note, the speed controller internal
electronics are actually waterproof but the cooling fan can be damaged by excess
water, no RC car chassis is waterproof and drive line and bearing damage is inevitable in
water, it’s unlikely the rest of your electronic components are waterproof so we strongly
recommend that you don’t use your model in water)
2. Specially designed for RC car with excellent start-up, acceleration and linearity
features.
3. Compatible with sensorless brushless motor.
4. Multiple protection features: Low voltage cut-off protection for nimh battery / (with
the optional LED programmer LIPO Low voltage can be selected) Over-heat protection /
Throttle signal loss protection / Motor blocked protection.
5. Easily programmed and compatible with pocket-sized program card. (NOT INCLUDED)

Instructions Speed Controller
1. Connect BEC wires with the receiver (Number 3 in the diagram previous)
2. Connect motor wires with ESC (Number 1 in the diagram previous)
3. Turn on the transmitter (the hand held device that came with your car)
4. Connect battery pack with ESC then switch on the ESC. (Number 2 in previous Diagram)
5. When the connection of motor and battery is finished, the motor emits “Beep-Beep” tone.
6. When the throttle stick is in the neutral position, the motor re-emits “Beep-Beep” tone.
7. The ESC is now ready.
Instructions Motor
1. Install motor in the car taking care to use motor screws that are not too long or internal winding
damage could occur. We cannot give a recommended screw length due to the variable
thickness of RC car motor mounting plate. As a rule of thumb a motor screw that when inserted
into the motor plate without the motor should not protrude more than 5mm.
2. Install the pinion gear onto the motor. We recommend that the pinion size is reduced
compared to the standard brushed motor included with the car. So if the car came with a 20t
pinion we suggest trying an 18t as an example. We cannot suggest a pinion size as car drive trains
and chassis weight vary so much. If in doubt install a small pinion and work your way up to larger
pinion to avoid potential over heating problems.
Trouble shooting
1. If after powering on, the motor does not work and no sound is emitted, please check the
connections between battery pack and motor.
2. If after powering on the LED flashes, please check the voltage of the battery pack, which
should be from 5V~13v (lithium battery should be above 6.2v (2S Battery) 9.3v (3S Battery).
3. If the motor emits a “Beep-Beep” tone only, please check all the connections: BEC wires ,
transmitter and receiver, throttle signal wires, etc. please check the transmitter TH.TRIM and
adjust it to the motor re-emits “Beep-Beep” tone
4. If the car can’t be speed up, please check either voltage of the battery pack is too low or the
temperature of ESC is too high. If the voltage of the battery pack is too low, please replace the
battery pack. If the temperature of ESC is too high, please check all connections. If not, please
push the button EPA on your remote control.
5. If the car stops suddenly while in working state, please check the motor’s connections, and the
roadblock.
6. If the car runs in the opposite direction, which the transmitter is available, please swap two
wire connections between the ESC and the motor.
Adjustments with the optional LED program card.* (available separately)
1：Low Voltage Cut-Off: The function is mainly to prevent a lithium battery pack from over
discharging. The Speed controller is delivered with a 3.1v cut off per cell for lithium batteries. This
setting may mean that an early shut down is possible when using NIMH, Ni cad or other batteries.
(Setting can be changed with the LED Program card which is optional).
2：3 start modes (Also called “Punch”) from “soft” to “very aggressive”（default value Medium）
3：Maximum brake force: 25%, 50%, 75%, 100%（default value 50%）
4：Maximum reverse force: 25%, 50%, 75%, 100%（default value 25%）
5：Neutral range: 9% (narrow), 6% (Normal), 12% (Wide) (default value 9%）
