The SPIDER Automation 24V 500W MY1020 Motor Controller is an electronic control unit designed for compatible MY1020 brushed DC motors used in electric bicycles, electric scooters and other suitable electric mobility applications. It manages the motor’s electrical operation and provides interfaces for the accelerator, brake, battery, charging circuit, brake light and power-lock connections.
Designed for a 24V DC electrical system, this controller is listed for a 500W MY1020 motor application and has a specified current limit of 33A. It also includes an under-voltage protection threshold of 20V. Its compact housing measures 83 × 70 × 38mm and has a listed product weight of 215g. For reliable integration, the motor, battery and connected accessories must be compatible with the controller’s electrical ratings and actual wiring configuration.
Product Overview & Motor Control Function
A brushed DC motor controller regulates the electrical power supplied to a compatible motor and manages its operation according to the connected control inputs. In an electric bicycle or scooter, it acts as the central interface between the battery, motor and accelerator, allowing the rider’s speed command to control motor operation.
This model is specified for the MY1020 500W brushed DC motor. Alongside the primary motor and battery connections, it provides connection provisions for the accelerator, brake, charging circuit, brake light and power lock. These interfaces support integration into a compatible electric vehicle electrical arrangement.

Electrical Ratings & Under-Voltage Protection
The controller is specified for a 24V DC system and a 500W motor application, with a listed current limit of 33A. These ratings should be considered together when selecting the battery, motor and associated wiring. The actual operating current depends on the motor load and operating conditions; the listed current limit should not automatically be interpreted as a continuous current rating.
The integrated under-voltage protection threshold is specified as 20V. This is a controller protection parameter, not a battery charging voltage or a recommended routine discharge target. Battery selection should account for the battery chemistry, nominal voltage and fully charged voltage, as well as the controller’s permitted input range.
Multi-Connection Vehicle Integration
The controller provides connection provisions for the main drive system and selected vehicle accessories. The identified functions are summarised below.
| Connection Group | Purpose |
|---|---|
| Motor | Connection to a compatible MY1020 brushed DC motor. |
| Accelerator | Receives the rider’s throttle or accelerator command. |
| Brake | Provides an interface for a compatible brake-control signal. |
| Battery | Connects the controller to the compatible battery supply. |
| Battery Charging | Provides a designated connection provision for the charging circuit. |
| Brake Light | Supports integration with a compatible brake-light circuit. |
| Power Lock | Provides an interface for a compatible power-lock or ignition-switching arrangement. |
These are functional connection descriptions rather than a terminal-level wiring guide. Exact wire colours, connector types, polarity and pin assignments must be identified from the actual controller markings or its wiring diagram before installation.
Compact Housing & Mechanical Design
The controller has a compact enclosure measuring 83 × 70 × 38mm and a listed weight of 215g. Its form factor is suitable for installation in appropriately sized electric bicycle and scooter controller compartments.
The housing should be mounted securely, with sufficient space for the wiring to be routed without pulling on the connections. Protect the controller and its wiring from mechanical impact, abrasion and direct exposure to moisture. No specific ingress-protection rating is provided.

Connection & Operating Recommendations
Correct installation requires matching the controller to the MY1020 motor, battery and vehicle accessories. Since the supplied product information does not include a terminal-level wiring diagram, use the connection diagram or markings provided with the actual controller when identifying individual wires and terminals.
- Match the 24V System: Confirm that the battery’s full-charge voltage and operating range are suitable for the controller before connecting it.
- Confirm Motor Compatibility: Use the specified MY1020 500W brushed DC motor application and verify the motor’s electrical requirements.
- Consider the Current Limit: Account for the listed 33A current limit when selecting the battery, wiring, connectors and associated electrical components. Do not assume it represents a continuous operating-current rating.
- Observe Under-Voltage Protection: Treat 20V as the listed controller protection threshold, not as a charging target or routine battery discharge recommendation.
- Identify the Wiring Correctly: Confirm motor, battery, accelerator, brake, charging, brake-light and power-lock connections using the actual wiring documentation.
- Check Accessory Compatibility: Ensure that connected switches, lamps and brake-light components are suitable for the controller’s accessory interfaces.
- Secure the Controller: Mount the housing firmly and route cables to prevent abrasion, sharp bends and strain at the connections.
- Test Before Regular Use: Check accelerator response, motor operation, brake input and accessory functions under controlled conditions before operating the vehicle normally.
