Direct Drive Motor Small Size Low Weight Optimal Speed Control Absolute Value Encoder
Direct Drive Motor, is a type of permanent-magnet synchronous motor which directly drives the load. When using a this kind of 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 they only need low torque to accelerate the motor compared to geared motors, which have a lower torque to inertia ratio.
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.
