How to choose the right elevator motor?

To choose the right elevator motor, consider load capacity, speed requirements, power rating, motor type, control system compatibility, and safety features. Consult with experts for guidance in selecting the appropriate motor.

With the development of the economy, science, and technology, high buildings gradually rise, and at the same time, the elevator has gradually become an indispensable and important piece of equipment for people's modern lives. The most important piece of equipment in the elevator is the motor. The motor is an important piece of equipment to drive the elevator operation. The operation of the elevator is very important, so it is necessary to select the appropriate elevator motor.

Duty cycle analysis

An in-depth analysis of the expected daily and hourly traffic flow and frequency of use of the elevator is carried out. In addition, it is necessary to take into account the flow of people during peak traffic hours, such as the morning and evening rush hours in office buildings. High-usage applications require elevator motors that are capable of truly continuous operation as well as frequent starts and stops.

Load and torque

The motor must be sized to provide sufficient starting and running torque to match the application. When the elevator accelerates, the starting torque needs to overcome the weight of a fully loaded car, including the maximum number of passengers. Consider also the additional load of the counterweight used to balance the elevator car. The running torque must be able to keep a fully loaded elevator stationary.

Speed and time

The rated speed of the motor directly affects the performance of the elevator. The speed of the elevator is generally different for different usage scenarios, such as when the speed of the home elevator is generally slower and the elevator in the office area is faster. Different types of elevators also have different speeds. Elevators have a time limit, you need to know how high the elevator needs to go and how long it will take to get there, in addition to making sure that the motor is able to provide a smooth and controlled acceleration ramp until it reaches the maximum required speed.

Motor Type Comparison

AC induction motors are an economical choice that are often used in commercial or residential elevators, and the voltage they use is usually high as well. DC motors are also very common in elevators. Not all motor types are suitable for elevator motors; it is critical to consider the starting torque required by the elevator, the type of elevator service, and the speed and frequency of the ramp.


In addition to the above considerations, the ride experience also needs to be taken into account, such as ease and comfort of use, low noise during acceleration and deceleration, not disturbing the user, and simple maintenance.
