What makes a motor high torque?
A high torque motor is toroid shaped, like a donut, and thus has a large diameter and short axis. These motors can directly drive the application without additional mechanics, like worm wheels, belts or pulleys.
What determines the torque in a DC motor?
Torque of a motor is directly proportional to current. Therefore, the maximum torque a motor can produce is limited by the maximum current it can handle. The maximum steady state current a motor can handle is limited by the heat it can safely dissipate, which is proportional to the square of the current.
How do you build motor torque?
Increased displacement is the easiest way to achieve increased torque. Very large cylinders and a long stroke offer the greatest cylinder volume and overall piston area for the fuel charge to push against the crankshaft or lever, if you will.
Which is proportional to the torque in dc motor?
For DC Machine, torque is directly proportional to armature current and flux. In dc shunt motors, flux is constant (not dependent on armature current). Hence torque is proportional to armature current.
How do you control the torque of a DC motor?
The torque (and speed) of a DC motor are both controllable. The torque is controllable up to the maximum rated torque of the motor, and is controlled by varying the armature (and if a shunt wound motor, the field) current. Maximum sustainable torque is achieved at full rated current on the armature (and field).
Can you increase torque without increasing horsepower?
You cannot have horsepower without torque, but you can have torque without horsepower! … The most simple means of increasing torque is to run an open exhaust and intake and tune properly. Torque value will increase right along with HP, so long as the tuning is performed properly.
