An electrical tool called a motor starter is used to safely start and stop motors. The motor starter turns the electricity on and off just like a relay, but it also protects against thermal overcurrents. A motor can be securely started or stopped, its direction can be changed, or it can be shielded from low voltage and overcurrent using a motor starter. 

Two primary parts work together to safeguard and manage the motor in a motor starter: The electrical contractor and the overload protection circuit. Depending on the various sizes and ratings of the motor (an AC motor), motor starters come in a variety of ratings.

Types of Motor Starters

There are a variety of motor starters available in the market, depending on how they are connected in a circuit.

DOL or Direct On Line Starter

The most basic and widely used kind of motor starter is the Direct On Line (DOL) starter. It works well with small motors because a large spike in current won't have a significant negative impact. The motor is connected directly to supply lines since there is no need to lower the voltage to it during startup. While it does not lower the starting voltage, it shields the motor from low voltage, overloading, and single phasing.

Magnetic Starter

A connected motor load can be started and stopped using a magnetic motor starter, which is an electromagnetic device. An overload and an electrical contactor make up magnetic starters, which safeguard against an unexpected power outage. For magnetic motor starters to close and maintain the contacts, a coil must be powered. When there is a power outage, the magnetic starter immediately closes the control circuit and opens the holding contacts, cutting off the motor's power. It is a type of DOL starter. 

Manual Starter

It enables the motor to be turned on or off by the user. A switch that breaks or opens the circuit to start or stop the motor is part of the mechanism that powers the button. In the event of a power outage, this kind of starter keeps the control circuit intact. 

Star Delta Motor Starters

The star delta starter is used more frequently than other starter types. To lessen the voltage drop on the electrical supply line, they lower the start current given to the motor at startup. The motor windings are physically rearranged to reduce voltage during Wye-Delta, or Star-Delta, starting. The motor's windings are coupled in a Wye/Star arrangement at startup, which lowers the voltage across each winding. This also results in a three-fold reduction in torque.

FASD Motor Starters

FASD stands for Fully Automatic version of Star-Delta and thus is the better version of Start Delta motor starter types. A timer is used to help switch from star winding to delta winding and features a contactor and relay combo for pump sets' overload protection and ON/OFF operation.

Factors to Consider Before Buying Motor Starters

Motor starters are no different from motors, which come in a variety of sizes and power levels. Here are a few key considerations to keep in mind while choosing a motor starter:

Motor Compatibility

The voltage, current, wattage (horsepower) and frequency ratings of the starter must match those of the motor that is being utilised. Make sure that the voltage of your electrical system and the motor starter are compatible. Selecting a drive that is incompatible with the motor may cause the motor to malfunction and lose some of its performance and efficiency. 

Overload Protection

When a motor draws more current than it can manage, an overload happens. This leads to the motor overheating and eventually failing. Also, a motor starter guards against overloads. A thermal overload or an electronic overload protection device that is a component of the motor starter usually provides overload protection. These devices keep an eye on the current going to the motor and trip the starter if it rises beyond a predetermined threshold and stays above it for a predetermined amount of time.

Control Voltage and Interface Options

Choosing a motor starting with a current sensor whose thresholds can be adjusted via the operator interface without having to open the starter enclosure is a simpler and safer maintenance alternative to opening the motor starter every now and then. Choose motor starters with built-in power metering, advanced motor protection, and user-friendly interfaces, among other features that are usually added to other motor starter devices. Also it is recommended to check the voltage ratings to make sure there are no mismatch problems with the motor.   

Enclosure Type

The enclosure's design, along with its on/off, jogs, and other motor functions and NEMA rating, may guarantee simple operation for its users and safeguard the internal components from moisture, dust, and other elements. 

Short-circuit Protection

An electrical current flowing down an unapproved path, like a broken cable or a malfunction in the motor winding, is called a short circuit. High current flows from short circuits have the potential to harm the motor and other electrical system components. Usually, a fuse or circuit breaker that is a part of the motor starter provides the short-circuit safety feature.

Maintenance Cost

Unlike the equipment's original capital cost, maintenance is an ongoing expense that never truly quits. Thus, consider the type of motor starter specifications before installing it with your motor.

FAQs About Motor Starters

Q1. Which voltage and current ratings are available for motor starters?

Motor starters offer a broad range of voltage and current ratings to match various motor applications. Usually, the voltage rating covers a range of voltages, from lower 110V and 240V to higher 600V and 480V. 

Q2. Is it possible to connect multiple motors to a single motor starter?

Yes, a single-motor starter can be used on multiple motors only if they are of the same sizes and are mechanically coupled. All the motors should have their own overload protection. 

Q3. Will VFD (Variable Force Drive) replace the motor starter?

VFD can control both voltage and frequency and thus can be used as a motor starter, but it reduces speed and efficiency.  

Q4. What should I consider about motor starter installation?

It's critical to take into note the motor's physical space requirements as well as any weight or vibration restrictions. 

Q5. What are the components of a motor starter?

A contractor, an overload relay, control circuitry (which includes start and stop buttons), and a protective casing are the standard components of a motor starter.
