LANDE EM50S 55A 1000W BLDC Sine Wave Controller for Electric Bike mid Drive Motor Speed Controller with Hall Sensor

Overview

The LANDE EM50S 55A 1000W BLDC Sine Wave Controller is a high‑performance speed controller designed specifically for mid‑drive electric bike motors. Engineered with advanced sine‑wave technology and a built‑in Hall sensor interface, it delivers smooth, quiet acceleration and precise torque control for a superior riding experience.

Key Highlights

• Powerful 55 A continuous current rating – ideal for 1000 W motor setups.
• Sine‑wave output ensures silent operation and reduced motor vibration.
• Integrated Hall‑sensor support for accurate speed and position feedback.
• Compact, lightweight design fits easily into most bike frames.
• Wide input voltage range: 36 V – 48 V (compatible with 10S‑12S Li‑ion packs).
• Multiple protection features: over‑current, over‑voltage, under‑voltage, over‑temperature, and short‑circuit.
• Adjustable parameters via built‑in programming interface (PWM, regenerative braking, throttle curve).
• Water‑resistant (IP65) housing for all‑weather riding.
