Good braking characteristics: Soft start and soft stop can eliminate the need for existing mechanical or electromagnetic braking devices 2. High efficiency and low energy consumption: no excitation loss, no brush friction loss, no commutation spark, high efficiency and energy saving. Excellent torque characteristics: Excellent torque characteristics, good torque performance at medium and low speeds, high starting torque, low starting current, and strong overload capacity. Paired with an exclusive adaptive speed controller: fast start-up and response speed. In the case of an AC motor with a frequency converter, its high cost-effectiveness advantage can be further highlighted, and the wiring is convenient and can be used immediately upon power on. Voltage: DC 24V Shaft diameter:8/10/15mm Optional. Please check with y. We are not responsible. OR, you may choose to have a replacement.
