Your question: What care should be taken while installing a motor?

Make sure your motor will be kept in clean, dry conditions and away from sources of shock or vibrations. In the storage area, aim to maintain an ambient humidity of 60% or below, and an average temperature between 10 and 50 degrees Celsius.

What are the important considerations regarding motor installation in a workshop?

important considerations regarding motor installation wiring 1. All equipment used shall be of iron clad construction and wiring shell be of armoured cable or conduit type. 2. Looping of conductors and use of joints shall not be done 3.

What factors should be considered before installing motor controls and equipment?

Several items need to be considered in order to properly install and wire an electric motor drive and motor circuit. The motor controlled by the electric motor drive, system power quality, safety, installation factors, and both power and control wiring all need to be checked for compatibility with the motor and drive.

What are the steps taken to provide electrical safety guidelines for motor?

Safety for single phase motors

Conduct a proper inspection of the motor winding. Perform a power supply test to determine whether there is any problem by the motor. Do not leave a short-circuited battery for long because it would eventually explode. Do not power the motors beyond 12 volts.

What should you always do before working on an electric motor?

Safety Rules

  1. You should always keep your work area clean and well lit.
  2. All motors include many small parts; keep very young children away from your work area.
  3. Motors spin very fast; always wear safety goggles.
  4. Super Glue, provided with most of the kits, is “instant bonding”.

In what environment should a motor be installed?

Make sure your motor will be kept in clean, dry conditions and away from sources of shock or vibrations. In the storage area, aim to maintain an ambient humidity of 60% or below, and an average temperature between 10 and 50 degrees Celsius.

What is a major precaution for series motors?

Do not pull or pinch lead wires while the power is on. This may can cause an electric shock. Also, do not touch connectors or other live parts while the power is on. Failure to observe this may result in electric shocks.

What are the factors to be considered in connecting a motor?

Motor connections –– A motor connection should be made based on the information found on the name plate of a motor. The name plate of a motor contains information such as horsepower, service factor, voltage, and full load current rating.

What is most appropriate for final connection to a motor?

Standard practice is to make the final connection to the motor using liquid-tight flexible metal conduit (a.k.a. “Sealtight”), to allow for vibration.

Why do we need motor control?

They help the motor start in low-voltage conditions, allow multiple-speed or reverse control operations, protect from over current and overload faults, and perform a wide range of other functions.

What are three types of motor protection devices?

Types of motor protection device

  • Overload protection.
  • Short circuit protection.
  • Over temperature protection.
  • Under Voltage protection.
  • Phase failure and reversal protection.

Why is safety needed in an organization?

A safe and healthy workplace not only protects workers from injury and illness, it can also lower injury/illness costs, reduce absenteeism and turnover, increase productivity and quality, and raise employee morale. In other words, safety is good for business.

What does insulation type of class refer and how many classes are there?

There are basically four classes of insulation – A, B, F and H – class F being the most commonly used. These insulation classes were established to meet motor temperature requirements found in industrial applications.

What precautions should be taken when working with a DC motor?

Speed regulation in the series motor is quite poor. With the increase in the load speed of the machine decreases. (DC shunt motor maintains almost constant speed from no load to full load). DC series motor should always require to be loaded before starting the motor.

Why starter is needed to start a DC motor?

Starters are used to protect DC motors from damage that can be caused by very high current and torque during startup. They do this by providing external resistance to the motor, which is connected in series to the motor’s armature winding and restricts the current to an acceptable level.
