Speed Control Motors

Speed Control Motors
For applications where variable speeds are necessary, typically an AC motor with an Inverter or brush motors are used. Brushless DC motors are an advanced option due to their wide speed range, low heat and maintenance-free operation. Stepper Motors offer high torque and smooth low speed 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 Motor, Which is Better?
Low Heat / High Efficiency
Brushless DC 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 motors offer 80-4000 r/min with a flat torque curve allowing for constant speed with varying loads.
Motor Footprint
Brushless DC 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.

Features of Brushless DC Motors
Our new brushless DC motor allows for maximum design efficiency with an AC input driver selection. Designed to meet an IP66 rating, inch or metric, stainless steel gear shafts, one motor cable connection and a wide variety of wattages and gear types are offered to meet industrial needs.
Brushless DC Motors offer built-in Hall Effect sensor feedback for speed verification to maintain closed-loop speed regulation. In addition to controlling the motor speed, torque limiting (BLE2) and speed range limit setting, the drivers also offers an alarm function in case any problem occurs during operation.

Same Motor / Select Driver
The new brushless DC motors (BLE2 and BMU) feature the same motor with two driver options based on your application needs.
New Design (BLE2 and BMU Series)
IP66 Degree of Protection
Utilizing an industry style compact connector, a direct connection between the motor and driver can be achieved, no secondary connections. Connection is easy with the lock lever that does not require screws.

Standardized Stainless Steel Shaft
SUS303 type steel, which provides excellent rust prevention and corrosion resistance. Stainless steel is also used in the parallel keys and installation screws

Inverters with Three-Phase Gear Motors
AC gear motors with inverters allow for simple speed control by changing the input frequency or input voltage.
Our KIIS Series has been optimally designed for accurate speed control. For larger motor needs, our Brother ie3 motors offer high efficiency motors with Hypoid / Helical gearheads in parallel or right angle mounting configurations.
For smaller, compact closed loop applications (6 - 90W), Oriental Motor offers a closed loop package (DSC Series). For larger (100-200W up to 3 HP) requirements, our Three-Phase AC motors with a Frenic-Mini C2 Inverter is ideal.

KIIS Series Three-Phase AC Induction Motors
The Three-Phase KIIS Series offers an optimally designed, high efficiency next generation Three-Phase motor that incorporates higher strength gears, both Parallel Shaft type and new Hypoid Right Angles type that maximizes the motor performance. The KIIS Series is available from 100 W (1/8 HP) up to 200 W (1/4 HP) and features either a parallel or hypoid pre-assembled gear head.
High Performance
Characteristics have been improved to create a high-performance motor with little speed reduction even with a large load.
Fanless Design
KIIS new motor design reduced heat generation. With higher efficiency there is less heat generation in the motor so a cooling fan on the back of the motor is no longer required. With no cooling fan, dust is not blown around.
Brother Gearmotor AC Induction Motors
These AC gear motors feature superior efficiency from hypoid or helical gears while offering greater torque output thereby allowing for smaller motors and greater energy saving.
The gears in these AC gear motors are high strength, maintenance free and can be mounted in any direction with their slip fit "O" ring design. High reduction ratios, flange mount or foot mount types, right angle or hollow shaft right angle types available.
Premium Efficiency Series ie3
The new ie3 premium efficiency gear motors cost less to operate and demonstrate clear benefits when running for long periods of time (when compared to ie1 standard efficiency gear motors).
High-Efficiency Hypoid / Helical Gearheads
Compared to commonly used worm gears, High efficiency gear motors feature Hypoid / Helical gearing technology that can maintain efficiency above 85% throughout the motor's wide speed range.
