Do DC motors have different sizes?
DC motors are available in a wide variety of sizes, ranging from tiny motors for miniature devices up to and including large industrial motors capable of many horsepower.
How do I identify my Baldor motor?
The ID tag, which features the Baldor logo, is affixed to the main motor housing in plain sight. On the tag is a variety of codes and electrical specifications, all of which aid in positive identification, as the same model Baldor motor may have different ratings, depending on the intended application.
What are the 4 types of DC motor?
There are 4 main types of DC motors:
- Permanent Magnet DC Motors. The permanent magnet motor uses a permanent magnet to create field flux.
- Series DC Motors. In a series DC motor, the field is wound with a few turns of a large wire carrying the full armature current.
- Shunt DC Motors.
- Compound DC Motors.
How do I choose a DC motor size?
Key criteria for selecting a DC motor includes first finding out what voltage is readily available for the application and what physical size the motor needs to be. Speed and torque can then be considered once these first two parameters are determined. 1. Voltage availability is a critical element in motor selection.
What makes a good DC motor?
The higher the voltage, the higher the torque. The voltage rating of a DC motor indicates the most efficient voltage while running. Be sure to apply the recommended voltage. If you apply too few volts, the motor will not work, whereas too many volts can short windings resulting in power loss or complete destruction.
What are the specifications of DC motor?

How much current does a 12v DC motor draw?
Thus current ratings are often given when the motor is stalled. At this point it is drawing the maximum amount of current and applying maximum torque. A low voltage (e.g., 12 Volt or less) DC motor may draw from 100 mA to several amperes at stall, depending on its design.
Which DC motor is preferred for elevators?
DC cumulative compound motor having high starting torque up to 450% depending upon the degree of compounding. The speed regulation is varying up to 25 ~ 30%. That’s why these motors are used in elevators.
