Motor Speed Controls

Motor Speed Controls

Manage the speed of AC and DC motors

Motor Controllers

Motor Controllers

Store and run programs and send signals to a driver to control the motion of a stepper motor

Motor Starters

Turn motors on and off and protect them from current overloads

Motor Drives

Receive signals from a motor controller and deliver them to your stepper motor

Motor Switches

Turn motors, lighting, and electric heat circuits on and off

Relays

Electrically open and close circuits to control power to lights, motors, and other equipment

Timer Relays

Turn machinery on or off after receiving an electrical signal that starts the timer

Motor Voltage Monitors

Electric Gearmotors

Electric Gearmotors

A motor and speed reducer in one to slow speed and increase torque in AC- or DC- power applications

Brakes

Control how much and how quickly your drive system slows down

Torque Limiters

Torque Limiters

Keep torque at or below a set limit to control tension or braking or protect machinery from overload

Clutch/Brakes

Control when to transmit power with a clutch and when to hold a load in place with a brake

Clutches

Start and stop the transmission of power to machinery

Electric Actuators

Electric Actuators

Push and pull loads with more precise positioning than air and hydraulic cylinders

Gear Boxes

Adjust motor speed to achieve the right torque for your machine; transmit motion at a 90° angle

Positioning Slides

Positioning Slides

A lead screw drives the carriage for accurate positioning in laboratory and production equipment
