Motor Starters

Motor starters are motor control devices specifically designed to safely start, stop, and protect electric motors from electrical overloads. These electrical devices ensure the smooth operation of motors by manually or automatically turning them OFF or ON and prevent them from drawing excessive current. A motor starter consists of a contactor and an overload relay that consistently control the power and monitor the current. Whether for small single-phase or double-phase motors or large industrial three-phase systems, motor starters are a foundational component in any motor control setup.

Why Buy Electric Motor Starters?

Buying electric or electronic motor starters offers unparalleled benefits in various ways. These control devices ensure the reliable and safe operation of electric motors and prevent costly damage and downtime. A motor starter improves the overall efficiency and lifespan of the motor and contributes to enhanced energy savings. Additionally, by using advanced motor starters, businesses can comply with safety standards. 

View Our Best-in-Class Motor Starters:

At Enrgtech, we offer a premium range of AC motor starters tailored to diverse industrial and commercial needs. Our selection includes:

  • Manual Motor Starters – A manual motor starter is an electromechanical device designed to start or stop motors manually. These control devices offer basic overload and short-circuit protection and are used for small motors where remote control is not required. 
  • Soft Starters – These starters reduce the stress on electrical systems by gradually increasing the voltage/current to the motor during startup. They provide smoother acceleration in a controlled manner and extend the motor life.
  • DOL (Direct-On-Line) Motor Starters – A DOL motor starter is the simplest and basic motor that connects the motor directly to full line voltage. It offers a cost-effective, safe, and reliable motor startup solution for small to medium-sized motors. 
  • Star-Delta Starters – These motors use star-delta configurations that limit the starting current. A star-delta motor starter is used for larger three-phase induction motors and reduces the current initially following the delta configuration for normal running. 
  • Reversing Starters – A reversing motor starter is designed to enable motors to operate in both (forward and reverse) directions. It features two electrically or mechanically interlocked contactors to prevent simultaneous closure. 

Typical Uses of Motor Starters:

Motor starters are typically used across a broad spectrum of industrial and commercial applications, including: 

  • Pumps
  • Fans and Blowers
  • Compressors
  • Conveyor Belts
  • Machine Tools
  • Mixers and Agitators
  • Packaging Machinery.

Altistart U01 The Altistart U01 is a soft start/soft stop unit for asynchronous motors. It is designed primarily for combinations with TeSys model U controller-starters. When combined with a TeSys model U, the Altistart U01 is a power option which provides the “Soft start/soft stop” function. The result is a unique, innovative motor starter. Using the Altistart U01 starter enhances the starting performance of asynchronous motors by allowing the motor to start gradually, smoothly and in a controlled manner. Control two phases of the motor power supply to limit the starting current and fordeceleration Internal Bypass relay Motor power ratings range from 0.75 kW to 15 kW Motor supply voltages range from 200 to 480 V, 50//60 Hz An external 24V power supply is required for controlling the starter. Schneider Electric TeSys U The TeSys U is a modular system for motor control; it enables the user to create a customised solution for their control requirements, from a series of standard modules. The plug-in modules allow the assembly and wiring before the selection of motor protection parameters and control voltages, they can be created or changed in seconds by changing the plug-in modules. A host of DOL starting applications can be catered for.
