What is a Direct Drive Motor?

A Direct Drive Motor, is a type of permanent-magnet synchronous motor which directly drives the load. When using a Direct Drive Motor, the use of a transmission or gearbox is eliminated. Therefore, the amount of moving parts in the system is reduced tremendously. This increases the efficiency and creates a quiet and highly dynamic operation as well as a very high lifetime of the system. Examples  of Direct Drive Motors are torque motors, linear motors and  certain types of BLDC motors.

Direct Drive Motors are very suitable for high speed, acceleration applications with fast starts and stops. This is because Direct Drive motors only need low torque to accelerate the motor compared to geared motors, which have a lower torque to inertia ratio. 

Furthermore, a Direct Drive Motor can also be supplied as a frameless motor. “Frameless” refers to a motor without a frame, housing, bearing or feedback system. Consequently, system suppliers are capable of integrating their motor into the application itself, eliminating the need for additional interfacing. This, of course, reduces the cost of ownership.

A Direct Drive Motor can be used for various applications, such as applications where a high positioning accuracy is needed. Moreover, these frameless motors are used for situations where small size, low weight, maximum power and optimal speed control is desired.
