Welcome to the store! 1. All-metal construction ensures durability, rust resistance, and extended lifespan. Copper wiring provides excellent electrical conductivity for smooth motor operation and high-temperature resistance. 2. Built-in encoder measures speed, ensuring consistent speed and transmission rates across all motors. Features two-channel and three-channel magnetic encoders with increased mileage, suitable for all harsh environments. 3. Heat-treated gears offer wear resistance, longevity, and low noise. The protective cover shields the encoder from dust and damage. 4. Each magnetic encoder includes a magnetic grid and a magnetic sensitive detection motor, outputting two channels of square waves with a 90° quadrature phase angle. Each motor provides 16 pulse signals per circle AB. 5. This encoder gear motor is ideal for massage chairs, electric ovens, medical equipment, electric baby shakers, paper shredders, electric doors and windows, and industrial drives.
