In-runner 28mm BLDC Motor


Industrial Machines, Vending Machines, HVAC , Computer Peripherals, Automation, Military equipments


QI Series Motors are Brushless DC inrunner motors with 28mm diameter. In these BLDC Motors a very compact driver mounted on back side of motor with facility of Forward/Reversed, PWM FUNCTION & Taco output functions as default. These motors are available in different speed and different voltage on special request. This motor is available in bush bearing with life of => 5000 Hrs. These Motors are used in combination with many Mechtex gearheads. Depending on the application, output speed, load applied etc the type of gearhead can be selected. Various types of gears i.e poly acetal, sintered iron, brass & steel gears can be used based on the load considerations. Poly acetal or sintered gears usually are used for noise dampening & complete poly acetal gears are used when the output torque required is less. All bearings are permanently lubricated and therefore require no maintenance.
