What are the parameters that affect high speed and high peak current in industrial power tools?

Battery-powered industrial power tools generally operate at low voltages (12-60 V), and brushed DC motors are usually a good economical choice, but brushes are limited by electrical (torque-related current) and mechanical (speed-related) The friction) factor will create wear, so the number of cycles in the service life will be limited, and the service life of the motor will be an issue. Advantages of brushed DC motors: small thermal resistance of coil/case, maximum speed over 100krpm, fully customizable motor, high voltage insulation up to 2500V, high torque.

High-speed stage: First, when the bolt is screwed in or the cutting jaw or the clamping tool approaches the workpiece, there is little resistance, in this stage, the motor runs at a faster free speed, which saves time and increases productivity. High Torque Phase: When the tool performs the more forceful tightening, cutting or clamping phases, the amount of torque becomes critical.

Motors with high peak torque can perform a wider range of heavy duty jobs without overheating, and this cyclically changing speed and torsion must be repeated without interruption in demanding industrial applications. These applications require different speeds, torques and times, require specially designed motors that minimize losses for optimal solutions, devices operate at low voltages and the available power is limited, which is especially true for battery powered devices The essential.

The structure of the DC winding

In a traditional motor (also called inner rotor) structure, the permanent magnets are part of the rotor and there are three stator windings surrounding the rotor, in an outer rotor (or outer rotor) structure, the radial relationship between the coils and the magnets is reversed and the stator coils The center of the motor (the movement) is formed, while the permanent magnets rotate within a suspended rotor that surrounds the movement.

Inner rotor motor construction is more suitable for handheld industrial power tools due to lower inertia, lighter weight and lower losses, and due to longer length, smaller diameter and more ergonomic profile shape, it is easier to integrate into handheld devices, Additionally, lower rotor inertia results in better tightening and clamping control. The coils are wound in slots around the stator, and the magnetic induction in the laminations is high due to the small air gap between the laminations (stator) and the magnets. Therefore, we can use a smaller magnet diameter, the volume of copper is limited by the slot, and it is difficult to wind in the slot, and the coil is installed in the stator slot to reduce the thermal resistance of the coil/stator assembly. When there is no current, the rotor has a preferred magnetic potential in front of the laminations, which can create a toothing or ratcheting torque. One way to reduce the ratcheting torque is to tilt the laminations. Since the coils are inserted into the laminations, a slotted motor very sturdy.

The slotted design (200°C) can withstand higher temperatures than the non-slotted design (150°C), resulting in higher torque. In most cases, however, the limiting factor for a power hand tool is the maximum temperature the tool can reach for extended periods of time (approximately 47°C max), which is a comfortable level for the operator, and in fact, prolonged heat can make holding the tool of operator discomfort, and safety regulations require that the maximum temperature be kept low.

The electrical performance of the motor is determined by the magnetic circuit

The first component (i.e. the magnet) can have a fixed value, but the second component (i.e. the copper winding) can be easily modified, by changing the wire diameter and the number of turns, the torque constant "kt" and resistance "R" can be fine-tuned . High-speed stage: The motor needs to run at high speed with low resistance, ω = (U – R * I ) / ktω (speed, in rad.s-1) U (voltage, in volts) R (resistance, in ohms) I (current in amperes) kt (torque constant in Nm/A), since the torque constant is in the denominator of the calculation, the lower the kt, the higher the rotational speed, which allows more operation in the same time period and increases productivity.

High torque stage: In the second stage, the motor mainly provides peak torque at low speed, according to the laws of physics, torque is the product of torque constant and current: C = kt * IC (torque in Nm) I (current in amperes) kt (torque constant in Nm/A) The higher the kt value, the higher the output torque at a given current. By adjusting the kt value of the motor windings, designers can optimize rotational speed or output torque to find a good balance between torque and rotational speed, thereby reducing overall duty cycle time. There is no unique solution, a compromise kt must be chosen to balance the performance of the motor at different operating stages. Based on simulation and experience, motor design can find optimal solutions during the coil design process. Copper losses and torque, we might consider choosing a lower kt value to increase the speed and compensate the lower kt value with a larger current (I) to achieve a higher output torque, however, a higher current Will increase copper loss, copper loss = R * I^2 The higher the current, the faster the motor and hand tool heat up, thus limiting the maximum torque available, the motor should be designed with as little current as possible to limit heat generation (handheld device temperature affects productivity) and extend battery life.

Iron loss and speed, iron loss affects speed, eddy current loss increases with the square of speed, even rotating under no-load conditions can make the motor heat up, high-speed motors require special precautionary designs to limit eddy current heating.
