What information is on a motor nameplate?

The nameplate lists the maximum ambient temperature at which the motor can operate and still be within the tolerance of the insulation class at the maximum temperature rise. It is often called “AMB” on the nameplate and is usually given in °C. Altitude.

What value is found on a motor nameplate?

The nameplate includes the based speed given in RPM. Base speed is where the motor develops rated horsepower at rated voltage and frequency. Base speed indicates how fast a fully-loaded output shaft will turn the connected equipment when proper voltage and frequency is applied.

What 4 piece of information on a nameplate must be followed when installing or replacing a motor?

Find the nameplate



That nameplate provides the following information: Model or catalog number. Serial number. Horsepower (HP) and speed (rpm)

What is FF on a motor nameplate?

Form Factor (FF)



Form Factor for a DC voltage electronic control is a measure of the amount of current (ampere) filtering (smoothing) provided by the control to a motor.

How do you tell if a motor is rated for a VFD?

Three major factors should be considered when determining if a motor is compatible with a VFD: the motor winding insulation, motor bearings and pump operating speed range.

How do I know if my motor is inverter duty rating?

Motor insulation systems that are rated for inverter use will be specified on the motor nameplate (or a sticker). These systems should have wire rated for a minimum of 1600 volt spikes, F or H class insulation, and will be processed with 100% sold resin in a vacuum pressure impregnation (VPI) system.

Which DC motor has maximum self loading property?

Which DC motor has got maximum self-loading property? Explanation: A differentially compound DC motor, flux reduces so sharply at small increase in load at higher values of load.

What is nominal power of motor?

The nominal power in kW (Pn) of a motor indicates its rated equivalent mechanical power output.

How do you tell if a motor is thermally protected?

How do I know if my engine is thermally protected? Thermal protectors generally reset themselves once the motor cools down to a safe operating temperature. There is usually a visible red button located on the wiring side of the motor—usually, though not always, located opposite of the motor shaft.

Which power is mentioned on a nameplate of a motor?

Which power is mentioned on a name plate of a motor? Explanation: Name plate of the motor shows rated values i.e. rated speed, rated current, rated voltage. It also shows output power available at shaft when all other quantities are set to rated values.
