'Direct Drive' can be applied to any motor which directly drives a load or rotor without transmission elements such as gears, pulleys or chains. More usually, the term refers to brushless, permanent-magnet, synchronous motors which transmit their torque directly to their load or rotor.
What is the advantage of direct drive motor?
One of the major advantages of using direct drive motors is increased positional, speed and dynamic accuracy. Rather than dealing with a coupling, gearbox, belts or chains, a direct drive motor attaches directly to the load so there is no hysteresis, backlash or 'lost motion' in any direction of movement.
Is a direct drive motor AC or DC?
Direct drive motors operate like most brushless DC motors. Magnets are attached to the rotor of the motor and windings are arranged on the stator, with the windings producing electro-magnetic fields as they are energised, which either attract or repel the rotor's magnets.2 Apr 2020
Is direct drive more efficient?
Generally speaking, in ideal conditions running on-highway over relatively flat ground, direct drive is the more efficient option.
What is a indirect drive?
Indirect drives use gears, pulleys, or chains to offset the motor shaft from the shaft turning the pump, providing the obvious advantage of being able to adjust the speed or rpm level of the pump shaft. Indirect drives can be configured to yield almost any motor/pump speed ratio.5 Feb 2016
What is a direct drive system?
Direct drive technology means that the motor power is transmitted directly and without intermediate components to the mechanical unit that is being powered. There are no drive belts, gears or similar parts.
What is a direct coupled motor?
Direct coupled (applied to an engine), drives a machine directly without intervening belts, chains, or gears.
How do you control a direct drive motor?
How do Direct Drive Motors Work? Direct drive motors work in much the same way as most brushless DC motors. Magnets are attached to the motor's rotor and windings are arranged on the motor's stator. As the windings are energized, they produce electromagnetic fields which either attract or repel the rotor's magnets.
