24V 350W Brushed DC Motor Controller for Scooters & Mobility Carts | FabiRide

The 24V 350W brushed DC motor controller is a pulse width modulation (PWM) drive module built for two-wire brushed DC motors. It runs on 24 V DC and handles up to 350 W of continuous motor power. Consequently, it suits electric scooters, electric and mobility wheelchairs, mini karts and basket carts.

Speed control comes from a standard 0-5 V throttle signal. Therefore, you can wire a thumb throttle, half-twist grip or full-twist grip directly to the board. The controller connects straight to MY1016, MY1018 and MY1020 class 24 V brushed motors. In addition, it works with 24 V lead-acid, lithium-ion and LiFePO4 battery packs.

A compact housing keeps installation simple in tight spaces. For instance, it fits under a scooter deck or inside a wheelchair frame. Moreover, soft-start and overload protection shield the drivetrain and chain from sudden load spikes.

Key Benefits

• Soft-start ramping – the motor accelerates smoothly, so the chain and gearbox take fewer shock loads at launch.
• Efficient PWM regulation – switching control delivers better efficiency and less waste heat than simple resistor-based speed limiters.
• Stable speed holding – motor RPM stays even while the load changes on hills and rough ground.
• Overload protection – the controller limits current whenever the motor pushes past the 350 W ceiling.
• Compact housing – the board fits in spaces where bulkier 48 V class controllers simply will not go.
• Wide battery compatibility – runs from 24 V lead-acid, lithium-ion or LiFePO4 packs without extra adapters.
• Universal throttle input – accepts any 0-5 V Hall-type grip, so your existing throttle stays in place.
• -10…+45 °C operating range – usable in cool weather, not only during the summer season.

Who Is This Controller For?

This module targets electric scooters, electric and disability wheelchairs, mini karts and basket carts. All of these vehicles run a 24 V brushed DC drive rated up to 350 W. As a result, the controller drops into most existing wiring layouts.

DIY builders also use it in low-power mobile machines with a 24 V DC motor. Typical examples include home-built cargo trolleys, chain-drive test rigs and children’s scooters fitted with an MY1016 class motor. Furthermore, MY1018 and MY1020 motors work equally well within the same power band.

One limit matters. This controller does not drive brushless (BLDC) motors. BLDC hub motors, common in modern electric bikes, need a three-phase controller with Hall sensor inputs. Before ordering, therefore, confirm that your motor has only two power leads.

Technical Specifications

Installation and Wiring

Check polarity with a multimeter before you connect anything. The red lead is positive and the black lead is negative. Reversed polarity can destroy the board instantly.

Use wire of the correct cross-section. At 24 V, a 350 W load draws roughly 15 A continuous current. Mount the controller where air can move around it, so heat escapes freely. Additionally, consider a fuse in the battery line sized to your working current.

Keep the throttle signal cable short, or use shielded wire. That approach reduces electromagnetic interference on the 0-5 V line.

Why Choose This 24V 350W Controller?

Simple switch-based setups either run the motor flat out or not at all. This board uses PWM regulation instead. The motor therefore builds speed progressively, and energy is not burned off as heat the way resistive speed limiters waste it.

Size is the second differentiator. Many 48 V class controllers will not physically fit a scooter deck or a wheelchair frame cavity. This compact unit does, while still delivering the full 350 W band with overload current limiting in place.

Finally, the universal 0-5 V input removes a common upgrade headache. You keep your existing thumb or twist throttle, and you keep your existing 24 V pack, whether it uses lead-acid, lithium-ion or LiFePO4 cells.

Frequently Asked Questions

Will this controller work with an MY1016 motor?

• Yes. MY1016, MY1018 and MY1020 class 24 V brushed motors all pair with this board.
• The motor must stay within the 350 W power ceiling.

Can I use it on a brushless hub motor?

• No. This is a brushed DC controller for two-wire motors only.
• BLDC hub motors need a three-phase controller with Hall sensor inputs.

Which throttle types does it accept?

• Any 0-5 V Hall-type unit: thumb throttle, half-twist grip or full-twist grip.
• Existing throttles usually connect without modification.

Does it suit an electric wheelchair or mobility cart?

• Yes. Electric wheelchairs, disability wheelchairs and basket carts with 24 V brushed drives are all supported.
• Mini karts and children’s scooters fall in the same category.

What battery chemistry can I run?

• 24 V lead-acid, lithium-ion and LiFePO4 packs all work.
• Nominal system voltage must remain 24 V DC.

What current should I plan the wiring for?

• Roughly 15 A continuous at full 350 W output.
• Size your cable and battery-line fuse accordingly.

Can I mount it outdoors?

• The unit is designed for internal mounting inside a frame or deck.
• Operating range spans -10 to +45 °C ambient temperature.

What happens during an overload?

• The controller limits current once the motor exceeds 350 W.
• Soft-start additionally reduces stress during every launch.

This PWM module gives 24 V brushed drives smooth acceleration, steady speed under changing load and current limiting in one compact package. Match it to a two-wire motor rated up to 350 W, confirm polarity, and it becomes a straightforward replacement or upgrade for scooters, wheelchairs, mini karts and cart projects.
