Features Of DC Gear Motors

Mar 14, 2017

·         Gear materials: Plastic or metal.

·         Motor types: Wound-field, permanent-magnet, brushless, intermittent and continuous duty motors.

·         Brush-type and brushless motors: The brushed motor gains torque from the power supplied to the motor using stationary magnets, commutation and rotating electrical magnets. Brushless motors use a soft magnetic core in the rotor or a permanent magnet, as well as stationary magnets in the housing.

·         Uncommutated motors: Homopolar motors or ball bearing motors.

·         Connection types: Shunt, series and compound connections.

·         Motor constants: Kv and Km.

·         Speed control and reversibility: Smoothly control a speed down to zero without power circuit switching, even after accelerating in the opposite direction.

·         Dynamic braking and regenerative braking: Ideal for applications that require quick stops so you don’t need a mechanical brake.

·         Magnet types: Rare earth, ceramic or ferrite magnets.

·         Winding resistance: Choose a motor that doesn’t adversely affect the Km.

·         Gear ratios: Several varieties available, such as 28:1 or 18:1.

·         Environment: Motors are available for indoor or outdoor use.

·         Torque multiplication: Generate a large force at a low speed.

·         Custom-built: You can have a DC gear motor designed and manufactured to suit your size, power, torque and mounting needs.
