This is the braked version of the MY1016ZL 24V 250W wheelchair motor, featuring an integrated 24V electromagnetic brake unit. It shares the same motor and gearbox specs as the standard MY1016ZL: a gear-reduced output of ~120 RPM loaded, capable of around 250 W of continuous power and roughly 20 N·m torque at the shaft, ideal for moving a wheelchair at walking speeds with a high load. The key addition is the electric brake module attached to the back of the motor. When the motor is not energized, the brake engages to lock the output shaft, preventing the wheelchair from rolling (for instance, on a slope or when the user is getting in/out). Upon powering the motor (or specifically, when the controller enables drive), the brake coil energizes to release the lock, allowing smooth motion. This brake is sometimes called an electromagnetic parking brake or E-brake; it typically consists of a friction disc or pad that is spring-applied and electromagnetically released.
From a performance standpoint, the brake adds a bit of weight (the unit weighs ~3.2 kg vs ~3.0 kg without brake) and a small additional power draw (the brake coil might draw ~1–2 A at 24V when engaged). The motor’s electrical characteristics remain: ~14.8 A rated current, ~4 A no-load, and the ability to run continuously under heavy load thanks to the integrated cooling fan and quality construction. The 17 mm output shaft with key slot is retained for directly mounting wheel hubs or sprockets. The brake mechanism is coupled to this shaft – typically, if power is lost or the joystick is released, the brake will stop the shaft from turning within a very short distance, ensuring safety.
In practical use, when installed in a powered wheelchair, two of these braked motors (left and right) give the user full control and also act as automatic “parking brakes” when the joystick is centered. This prevents the wheelchair from rolling downhill or being pushed unless the system is intentionally put into a freewheel mode (usually by a mechanical lever that overrides the brake for manual pushing). For builders, using the braked version simplifies design since you don’t need a separate brake mechanism on the wheels. The brake wires connect to the controller (most wheelchair motor controllers have outputs to drive the brake coils, releasing them when the user commands motion).
This motor can also be used in other mobile robots or carts where an automatic braking feature is needed for safety or precision (for example, a robot on a slope that must hold position when stopped). It’s a reliable, field-tested component found in many commercial wheelchairs. Proper wiring of the brake (observing correct polarity and voltage) is important – and note that if the brake is engaged, trying to power the motor without releasing the brake will stall the motor, so the controller must be configured to release brakes first.
