Speed Control Motors

For applications where variable speeds are necessary, typically an AC motor with an Inverter or brush motors are used. Brushless DC gear motors are an advanced option due to their wide speed range, low heat and maintenance-free operation.

Speed is typically controlled by manual operation on the driver or by an external switch, or with an external 0~10 VDC. Speed control systems typically utilize gearheads to increase output torque. Gear types range from spur, worm or helical / hypoid depending on torque demands and budgets.

Mounting configurations vary to depending on space constraints or design of the application.

 

 

Choosing the Right Motor: AC Gear Motor vs. Brushless DC Gear Motor, Which is Better?

Low Heat / High Efficiency

Brushless gear motors use permanent magnets in the rotor and produce low heat due to their high efficiency, are cleaner and are maintenance free because there are no brushes to replace. Brushless DC gear motors offer 80-4000 r/min with a flat torque curve allowing for constant speed with varying loads.

DC Gear Motor Power Consumption

Motor Footprint

Brushless DC gear motor’s torque density is higher than AC gear motors, allowing for a more compact design. Using hall effect sensors allows for closed loop control and maximum design flexibility.
