Direct drive motors are either linear or rotary motors, where the motor is an integral part of the mechanical assembly. This eliminates the need for mechanical transmission elements such as couplings, gearboxes or belt and pulley systems.
A direct drive motor can provide many benefits including:
Direct drive rotary motors work very similarly to most types of brushless DC motors. Magnets are attached to the rotor of a motor, with windings arranged on the motor’s stator (stationary part of a rotary system). As the windings are energised, electromagnetic fields are produced which attract and repel the magnets within the rotor. As the motor is an integral part of the mechanical assembly, this motion directly moves the payload.
Direct drive rotary motors are available in a hollow frame format to allow rotating shafts to be directly driven (shaft passes through the centre of a motor). Examples of direct drive rotary motors available from Heason Technology include:
A direct drive linear motor is essentially a rotary motor that is laid out flat, directly mounted on to the driven load. Magnets are energised in a linear sequence to attract and repel fixed magnets. This action causes the payload to move along the track. Examples of direct drive linear motors available from Heason Technology include:
