Easy Operation

Operate by Turning the Dial and Pressing

Turn the dial and set to the desired value. Set the speed by pressing the dial.

Speed Control Dial

Start, Stop and Switching the Rotation Direction

Starting/stopping and switching the rotation direction is done with a single switch operation. No external switches need to be provided.

Controls for Speed Control

High Reliability

Low Electrical Noise and Simple System Configuration

The motor and speed controller used in the US2 Series do not generate a lot of noise themselves. This means that little peripheral equipment is needed to suppress noise, which cuts down on equipment labor and costs and saves space.

High Reliability

Speed Control Using Closed Loop Control

Stable Operation Even if the Load Fluctuates

The tachogenerator built into the AC motor always checks the speed, so the setting speed is always maintained even if the load fluctuates. In addition, due to this switch to a digital control circuit, speed regulation has been improved from −5% to ±1%*.

Stable Speed Operation

Simple Wiring

Max. Extension Length 32.8 ft. (10 m)

Connecting the motor and speed controller is easy using a connector. The motor and speed controller can be up to 32.8 ft. (10 m) apart.
Simple Wiring

Built-In Capacitor

Since the capacitor is built in, wiring labor is reduced and space is not wasted.

Built-in Capacitor

Useful Functions

Smooth Operation when Starting and Stopping

The motor's acceleration time and deceleration time can be set with the acceleration/deceleration time potentiometer.

Setting time 0.1~15 seconds (the factory setting is 1 second)

The acceleration/deceleration time potentiometer must be enabled with the
FUNCTION key in advance.
The instantaneous stop function is not available.

Smooth Operation

Protection for Motor and Speed Controller

Alarms for the motor overheating, poor connection, locking, etc. are displayed to protect the motor and speed controller.

Use of High Permissible Torque, High Strength Gearhead

Parallel Shaft Gearheads

Utilizes a gearhead that excels in both permissible torque and strength. Special side panels in the gearhead have increase rigidity, and heat processing (carburization) has increase the strength of the gears.

Right-Angle Hollow and Solid Shaft Gearheads

25 W (1/30 HP)
40 W (1/19 HP)
90 W (1/8 HP)

Speed Control Motor Right-Angle Solid Shaft Gearhead Speed Control Motor with Right-Angle Hollow Shaft Gearheads

Uses high-strength hypoid gears. Compared to conventional products, torque has been greatly increased and noise has been reduced. Furthermore, the radial load and axial load on the gearhead output shaft have been increased, contributing to decreased equipment size and increased reliability.

Right-Angle Gears

Motor Mounted Perpendicularly to the Drive Shaft, Saves Space

Connect Directly to the Drive Shaft to Reduce Costs

Right-Angle Gearheads Reduce Parts

Installation Inside Conveyor Provides FurtherSpace Savings (Hollow Shaft Type)

Conveyor drive rollers can be installed on both ends of the load shaft of a hollow shaft type. The equipment can be made even smaller compared to when the motor is installed on the side of the conveyor.

Right-Angle Gear Hollow Shaft

Preassembled Motor and Gearhead

Reduces customer assembly time, and can be installed on equipment immediately.

The motor position can be rotated in 90° increments, and the lead wire pull-out direction can be changed. The gearhead can be purchased and replaced for maintenance or to change the gear ratio.

Rotate the Motor

Use of a torque arm allows for even further time and labor savings for installation

Connection / Extension Cables

These cables extend the distance between the motor and controller. Use flexible connection cable in applications where the cable is bent or flexed.

Torque Arm

A torque arm acts as an anti-spin mechanism when a right-angle shaft, hollow hypoid JH gear is installed to prevent gearheads from rotating due to reactive force from shafts being driven.
